It seems that you're using an outdated browser. Some things may not work as they should (or don't work at all).

Apparently this happening at steam release as well.
so the basic complaint is the drones just stop doing their jobs: building, repairing, removing, and mining.

I have tried saving the game quitting then re loading the saved game the drones do their thing for about 5 minutes then they just stop alltogether.

its becoming annoying to keep reloading everytime they stop.

is there a patch coming for this or should I just get a refund?
Hi there,
we are already on it, thanks to the contributions and details provided by the Sphere-Community.

There might already be another small hotfix today or tomorrow, to get this sorted. However, first we have to get this properly tested internally, just to be sure.

So stay tuned!
