Just after update 0.5.0.2752 December 15 2020 I just went to explore the pond and see Koi fish stuck at the entrance to power switch "C" , after a lot of trying and dying, not because the koi fish attack me, but because i got stuck between the koi fish and some rocks and ran out of air. But I manage to make koi move and quickly enter the area and turn the switch on and have a little trouble getting out because the koi fish is stuck there.
