Mods arnt working? in Solved Topics Posted August 5 · Edited August 5 by JJay Changed, topics have been Archived due to the Rules has been changed Hi Let's Die Together, First off welcome to TruckersMP's forums. In terms of your red circle next to the mod that means the version of ETS2 is unsupported therefore the mod will need to be updated to the latest version before it can be used again . Although as you say it only persists in multiplayer checkout the details below. In TruckersMP only base game content is supported. This is because if mods were supported people would have to download each individual mod and some players would feel left out that their own mod couldn't be included (Well over 1 million players!) due to storage.
