So I thought that if you have two custom liveries of the same wagon type (eg the US Tank wagon) then only one would show up in the service or journey mode and not both. If you see in the pic there's two. The Ron tank wagon and the CP Rail tank wagon as well as the original non painted wagon. The new WIP tanks. Regards Hentis
They said that wagon liveries would be randomised, back in the livery editor stream (or one of the related pre-release steams)
