Unsure what caused this but there were issues between my friends and I where sometimes a big chest when accessed would open but the ui would not appear and the chest would become stuck open. No other chests(big or small), personal inventories, crafting stations, nor the esc menu could be accessed but one could still open the ui for skills and the various tabs related to that. For record, I am the host.

I just joined to report the exact same bug!

Thirding this, my friend and i also encountered this
It happens to both me (the host) and him (the invitee)
But also happens with small chests in my instances
solid spruce
can confirm as that friend and also a visual glitch that happened at the same time. I am unsure if it's unrelated though as I only couldn't access the chests, the crafting stations were fine though I could not collect from them once done
