I've been having this error show up in a window and taking me back to the main menu at random moments (never on a raid, though) no matter if I'm moving items around my stash, my inventory, selling and buying to a trader or the flea market. At times, I've also noticed that even if it doesn't give me the error, items will start having loading loops on them and take at least 5 seconds to update to the location I've moved it to.
I also don't know if this is related but I'm also seeing invisible items with no previews that load forever, and if I wear them or add them to my gun, either my preview or my gun won't show up unless i restart the game and server, but I'll make this into a separate thread if asked.
