I'm having the same problem! It's so annoying
deconstruct some building, undo what r u build before bug happen. first i decide build 3 moonpool then after deconstruct third moonpool everything back to normal. bulkhead/hatch animation back to normal. max 2 moonpool. and i have 5 multipurpose, 1 scanner room, 2 observatories. that just for starter base. outpost is 1 multipurpose, 1 scanner room, 1 moonpool. i keep adding decoration, and check if the bug happen again..
