Title says all. When I enabled this, my construction drones had very, very little range. Like I had to stand next to stuff to get it to deconstruct and build.
This seems to be an issue with the normal hovercrafts mod, too.
I've tried to work out the issue. Send me a copy of your save file and I will do my best to resolve the issue. This has been an issue reported by other people involving another mod causing it too.
