I've been building a little house next to the sea and while I was building floors on the sea, I noticed that suddenly a floor of mine became bugged and I couldn't pass through it, I've tried building another floor on top of it but it hasn't helped.
The other problem was that I took my campfire materials (which had a lot of wood stored in it) and when I placed them again, my campfire info displayed nothing but an error message when I tried to click on it.
I've also noticed that when I try to fish with my spear, my character hits the ground instead of the ocean, I suppose it happens because I built my floor on top of the ocean.
