Chinese electric bus bug in BCS

BCS has a problem when it interacts with our electric buses. We've tested that only electric buses are affected. The diesel, gas and hybrid buses have no problems. And we've found something that can help to find where the bug is.

1. The bug happens when creating backups for .bus & .osc files in multiplayer and career mode for singleplayer. So we think it could be something related to failure simulation to repair, because free play doesn't add failure to buses. The typical phenomenon is BCS will be stuck at checking errors for maps (or in the middle of loading, if checking map errors are not activated) after selecting the buses. At this time the backup files are not created.

2. We've found a temporary way to use those electric buses, which is, when BCS is stuck at the position above, press "esc" and click "back", the buses can be loaded as usual, backups files are created.

3. In all of our electric buses, there are two that DON'T have this bug, which is not common. We've checked them with other buses from the same creator and same brand. They use almost the same .osc files, which means they are almost the same as the bug buses. We can't see the difference between them.

4. We use folders to category all the files. We had another bug which might be caused by the folders, which is, some variables for failure can't be added to the varlist.txt. But we fixed this by adding variables manually. I don't know if the folder can also be a cause for this bug.

So our conclusion is that there may be a weird process when creating the backup files for failure. It seems to be a bad file path finding or something, because there's no bug driving in game.

Quote from [PeDePe] Daniel T.

perhaps the affected buses have special characters of some kind in their names, file names or folder names that BBS can't cope with.

which files does BBS load and/or change while playing? we will check these files carefully again

and just another idea: i know BBS adds some codes for failure into osc files. is it possible to know whether it's stuck at loading/writing/saving process, so that we can know whether to check the name or the inside of the file?

I've checked the names. No special characters. We all name them with English letters and symbols on English keyboard.

And, I just remembered that no issues while loading in singleplayer -> freeplay. So there should be no name problem, at least in {friendlyname}

i don't know if the bug below is related. Please read the end first.

I just realized a bug about bad path/file finding logic of BBS.

Quote from CaptainZhang

We had another bug which might be caused by the folders, which is, some variables for failure can't be added to the varlist.txt. But we fixed this by adding variables manually.

So this was a bug i mentioned first. Now i think it's involved in the bad logic.

In some folders (in this bus folder), some buses have alternative versions of osc files. Take cockpit as an example, as it's changed by BBS.

We have like cockpit - blabla.osc and cockpit - blablabla.osc. BBS doesn't recognize which one is used by the current bus but changes both of them, making the other change unnecessary.

Also, for this osc it should add a BBS_Chat_Offen into the varlist. But it doesn't recognize the varlist in this folder and leaves a fault variable.

And next is the lights.osc. BBS doesn't put the new-added variables in the varlist in its folder.

But i wonder why the heizung and wiper works very fine when BBS adds codes and variables. And I just found that some osc for heizung are not changed too.

PS: we call it wiper_varlist. But for cockpit and lights we call it varlist, as it's already been sorted into the cockpit and lights folder, same as wiper.

and next, we have some old buses that uses a script folder outside the bus folder. It seems that BBS can't recognize where the scripts are. The script there are never changed for the failures. Therefore no bugs showed and we took a while to figure out what was happening above.

Now what i know is that cockpit, heizung, lights and wiper osc are changed by BBS. But I just can't see the real differences between the normal and buggy one.

There's a bus folder where exists a hybrid kind and an electric kind. The electric kind has the problem while hybrid doesn't. The only difference is the cockpit.osc (heizung osc is different but not changed here and i don't know why). It's "cockpit.osc" and "cockpit - E.osc" and I can confirm that the space in the name works.

-----------------------------------------------

Edit: just remembered the bus that uses the outside script folder. the electric one is buggy too.

And i noticed the freeplay also adds codes and creates backup (i was wrong about this) but no loading problem. What's the difference between freeplay and multiplayer&career? Only freeplay has no bug.

Could you tell how BBS finds and loads the bus? It's real hard to find the point now.

Edit: just checked a file called vorbereitung.log. It seems that all the electric buses are stuck and 26, after pressing esc and back load again it stops at 46.

But it says this after 38: Fehler beim Kopieren der org Datei: D:\Program Files (x86)\steamapps\common\OMSI 2\vehicles\[Public]YK6105 (access denied) when loading any Chinese buses.

Any idea about this?

no I didn't mean this. it's not about being modified.

it's a loading problem. BBS somehow gets stuck at this procedure.

i should have record a video if possible

bug report for BCS

this video shows how to produce the bug

Unfortunately, the image quality is too poor to see exactly what is happening

sorry, i just saw that if you don't log in at that website you will only see 320p quality.

i wanted to make it into zip file but it still exceeds 10MB.

i'll try to post it on youtube once again

Edit:

Please change the license plate to regular characters. AB-CD 1234

the license plate was AA-06845D. i just rent one with AB-CD 1234 but the bug still exists

Quote from [PeDePe] Daniel T.

this will cause possible errors.

no that's not the problem i think

as you can see there are some other folders with [public], which are not electric buses. they don't have the bug and load smoothly

but here these folders with red check marks don't have [], which are electric buses, they have the bug. and these are not all of the buggy buses.

but the folders in green circle are the electric buses that don't have the problem. they are the only three.

in the video, in hall 1, 17 and 19 are the buggy electric; in hall 4, 2 6 8 10 12 14 20 are. this is a huge amount. but hall 4 number 4 is the bus from the green circle.

i just wonder why this bug is on electric buses only.....

just did a comparison with a buggy one and a normal one

the difference seems to be obvious in bug.txt from line 96 to 124

i guess (?????) here is "access denied", the same as (拒绝访问。) in vorbereitung.log

i copied the console content when OMSI menu showed

i've tried some electric buses in my company and they're fine now.

i'll let my friends to try more buses later

it seems to be solved completely now. I'll report again if anything new happens.
