Was about to place one, but server restarted. I logged out, back in, wanted to place but noticed that I didn’t have any anymore… Was another guy in chat with the exact same problem.
I think empyrion changed in 5.0. You need to find Autominer cores out of alien bases un order to build them. SO I am sure the HWS devs removed everyones autominers.
You get a fat red warning to stop doing anything before server restarts. Data might not be saved.
Lessons learned maybe.
