Leaving a realm for any reason can lock growing plant pots.
Upon returning to the realm, any seeded and watered pots 'dry out' and can't be watered. The seed inside will not grow, either, locking the pot and seed until the pot is removed. The pot looks as though it isn't watered, but the mouse-over UI shows as if the pot is seeded and watered.
When I tested it, quickly relogging didn't trigger the bug, so maybe it has something to do with the realm with the pots unloading while I'm away.
Edit: Nevermind, it happened when I left the realm. Editing the report accordingly.
