Hey thx for your reply.
Yea the instalbiuld works perfect, only the "you plan the build first, than build" had issues.
I installed everything new and switched from R2Modman as my ModManager to Thunderstore and now, yeah, everything works perfect. Maybe there was a problem with a mod in the first time with the old manager, idk.
i would say the problem is solved, thx for your help :)
