well... my base is becoming more complete with time passing, I don't think i'll make it any bigger, so sad I couldn't completely seal the part of the generators, unless I remove or block one, which kind of hit heavy on my base energy...
I added some solar panels because of fog due mechas (which I had to go and destroy), but I ran out of food, there was a gillrot and the vats consume too much food.
BTW it has been more than 10 years in this colony, and I haven't seen a single sanguophage quest.
