Of the 4 chests, all but one are tagged as empty. I think this is an old issue.

However, my chest, the chest I've been sending camp supplies and items for other builds I might try this entire playthrough... Won't open.

It goes halfway through the opening animation, and then nothing happens. I've permanently lost access to everything in that chest. How has multiplayer been released for so long, and is still suffering from severe drawbacks?
