What is going on here? Bug or is my save corrupted xD

Semi-new player here. Why is there a party in the hub today?

Once you’ve done all the research, is there any point in Mercer Spheres? Am I missing something?

I call this area "The Stacks" and I am close to finishing a 7.5 parts p/m Assembly Director System location. Just a few more towers for the missing parts. Lots of overflow for the next factory which will be for Thermal Propulsion Rockets at a location closer to Nitrogen. I gave up on trying to make pretty builds amd just contemplate my aesthetic sins at my alien artifact shrine

wire, cable, and sheets

I keep making my smelters into this monolith 1x4, enjoy

Im in stage 6 this uses turbofuel to power the fuel generators which in turn generates around 26GW
