First let me start off by saying that I absolutely hate that the massage tables need power. The reason I hate this is because my dupes will try to use the massage table after running on the generator for literally 1 second. I have to disable the tables, allow the batteries to charge, then enable them. Then half the time, the dupes at 100% wont use the massage tables at all!
Build massage table, connect to batteries/generators, watch chaos.
