Steps of reproduction (it might just be the one camp stove, but I started and stopped dragging it several times)

1. Start dragging a stove (this one was lit underneath)

2. Put a pot on it

3. Go into a burrow and have it act...very strangely. It was considered "being dragged" and I undragged it several times, but it would only move upon relogging.

4. If you remove the pot, the camp stove will act normal again

Note: I'm not sure if it is even intended to be draggable at all, considering the "you can't pick it up whilst it's on fire" notification upon trying to pick it up. Likely applies to cauldrons as well.
