Have you bought furniture from the skyblock shop? If so, that is what's causing you're problems, it's a known bug and the team are working on resolving the issue.Since I started on my co op server about a week ago, there are 2 spaces in my inventory that I can't put anything into. I have to pull items by hand from my chests and be careful not to put anything in those spots or it'll spit them out when I close the inventory menu, help?
