So far in my experience this has happened in a medium tent & a wooden box
Items are getting stuck in the storage unit while transferring to hands/ swapping item in hand with storage item
I know it's happened to a lot of people because my friend taught me how to hotfix it (wooden box only) by carrying the box and logging out while holding it then logging back in, this is not possible with the tent.
I have been switching things between my hands backpack and storage only to have important items stuck in the storage unit.
This needs to be fixed immediately as this glitch makes what already is a terribly controlled and moderately difficult inventory system WORSE
