For those not yet using the 1.41 beta, all my trailers have issues because of a location change that SCS made with trailer parts/materials/textures.
Mods that I have updated yesterday and on the workshop are already fixed for this issue and they are the most popular mods.
The rest of the mods will take some time to catch up with, so in the meantime I have included this mod file that should fix all the textures in the other mods that still require updating.
This mod will likely fix other people’s mods that have the same issue too.
