Hi i love this mod i use it alot. but my game has started lagging when i walk near them and after a while the lagg disepear. but when i run by the drones it laggs so much. also removing them and adding normal mining things doesnt fix the lag.

You probably just have a slow PC,
Maybe you can send a save game with the lag and I can test it
