Edit: Bug takes shorter amount of time to happen
Edit 2: The bug will sometimes resolve itself, for no apparent reason.
Edit 3: The bug fixing itself seems to be temporary, lasting less than a minute.
As title says: whenever I sit in a single given area for 10-30 minutes or more, suddenly models stop loading in and emotes stop working, including the preview for the emote menu, where that shows a blank window.
Completely exiting and re-entering the game seems to be the only way to fix this bug. Apparently however, it seems the bug will randomly fix itself with no apparent cause for this fix, if temporarily for a minute or so.
