Bug 1 - golem's hand, I loaded a hand instead of a drill, which causes the drill to turn into a hand.
Bug 2 - the new golems of the Zahara faction use the same geometry as the old ones, which causes the old golems to break.
I'm happy with the current state of the mod, but to be honest, I'm willing to help if needed. However, I'm also a bit lazy and I'm working on the next unit, so if there's a way to avoid unnecessary actions, I'd be glad to do so.
