ProMods

Oh-kay, I'm not sure about the relation between ProMods and this bug, but it appeared after upgrading from 2.40+1.34 to 2.41+1.35. Everything was fine on the previous version. Russian license plates now lack their region number - as opposed to the ones in my signature e.g. If someone can report on these as well I'd be grateful; otherwise I'll take a closer look at what it might cause.

What other mods are you running? Could you please show us you're game.log?

Sorry for the late reply. I've been playing around with the game and found out that refreshing the custom number plates (which they are) for the truck on worldoftrucks.net fixed the issue for the trucks; the trailer is still bugged.
Apart from the map I'm also running your CAP and TCP; other than that nothing much, AI mods and minor cosmetics, e.g. "Real fridge manufacturers" or smth. I'll post a game.log as soon as I'll reach the PC.

P.S. I'd also like to note that I've been running the same mods in the same order before upgrading ETS, the only ones that were changed are PM, CAP and TCP.

@dikivan2000, does the game show the correct plate numbers/letters if you examine the trailer in the Trailer Manager window? I suspect the region code ("47" in your case) is shown in the Trailer Manager but it simply doesn't appear when viewing the trailer plate in-game.

It does appear in the Trailer Manager, yes. The plates are shown correctly everywhere except for the driving mode itself.

Finally been able to produce a game log, sorry for the delay.

Hello, CR929.

This bug is confirmed and fixed. It was reported already in internal bug tracking system with case #20546.
Anyway it wasn't in Trailer Mode, but some places did have wrong format.

Thanks for report

Sure is quite a nice necro if you ask me!
Totally forgot about this thing, but I really appreciate the message. May your testing and buxgfixing go smoothly
