So I've managed that the crane and the beams are created, but the final model is drawn, too.
e.g. if I build my new missile turret, the construction yard AND the completed (not animated) missile turret are drawn.
I can't find the difference to the original missile turret. Everything looks the same for me.
I don't know what I did wrong or didn't modify, yet.
During the beta I hadn't that problem.
