Pasi Kallinen 6530951fd5 Impossible timer after dipping a lit potion of oil 
Dipping a lit potion of oil into another potion could
turn the potion of oil into another potion; this resulted
in "burn_object: unexpected obj" impossible after the lit timer
ran out.

Just make an explosion if trying to dip a lit potion of oil.
