It actually is exactly like that.

By the way, when I actually remove the mod, I get a message lot longer, stating that all parts are missing. In its current state, it seems like only these 4 parts missing. There are some vehicles which contains a few parts from this mod (obviously not the ones listed), which are currently loadable. It feels like these particular parts are changed, deleted, or renamed (basically, not actually existing anymore, as they were) somewhere in development, so that my game cannot access them anymore. My save is around a year old. Or more..
(Before asking, I tried to reinstall it a few times, downloaded it from different sources etc. Parts are being shown at assembly buildings, and I can build new vehicles using them. The thing is, there are so many bases and saved stuff that I'd like to not lose, and in this current state, I can't even edit them and remove the missing parts, so.. Asking kind of too much, I know.)
