There should be some sort of way to turn on or off your liveries so that they don't appear in the AI in service mode. I have tons of liveries and sometimes I just don't like seeing them all the time. The only way to stop them from appearing randomly is to delete them which sucks.
It's not ideal, but the TSW2 Livery Master app will let you insert/remove liveries into/from TSW without deleting them (they're stored in a separate file). https://github.com/RagingLightning/TSW2-Livery-Manager/releases A pain to quit TSW* every time you want to make a change, but the best we can do unless/until DTG adds this functionality to the game. ______________________________________ *Do NOT use Livery Master with TSW running! You'll corrupt all your liveries and lose them
