The error seems to happen on your characters only, thats why it was so hard to trace ;p I suspect it had to do with the method used to drop followers. I created alternative code for dropping followers just now. You will notice that followers sometimes will need to rebless themselves after an area change (or their hp/ms may even get messed up), I will fix that later if this method will fix the depot error. Post if you get any trouble related to the storage or disconnects. You can also send me a message on discord so I can look into it right after it happens.
