Not sure if this is a bug but I'm exploring the Seal of Water, and after hitting the yellow tile in the bottom right room the chest fell into the water, but when I left the room and then returned, the chest was back out of the water but I couldn't interact with it. No idea what I'm supposed to do.
EDIT: Okay I figured out the puzzle, the box reappearing is purely superficial.
Also not a huge deal since meat is easy to buy but the unlimited food I got from the factory seems to have spontaneously disappeared from my inventory. Maybe I cleared that area sooner than I was supposed to?
