EDIT: Solved.
I used the drones in a wrong way. My mistake.
Dear all,
im not knowing how to use the Mod. But if I activate the mod, i can build "companion"-units. If i try to put something in my "modulare armor" its red or not allowed. If i put something else into it I got an error message and crash:
Die Mod Companion Drones 2.0 (2.0.1) hat einen Fehler verursacht, der nicht behoben werden kann.
Bitte informiere den Autor der Mod über diesen Fehler.
Error while running event companion-drones::on_player_placed_equipment (ID 41)
