Im convinced there is a bug regarding burning damage as well, although im not sure of the specifics. The burning mechanic seems very tempermental to begin with.
I've had characters die several times because during real time, they start taking burning damage, and instead of taking it every ~2 seconds, they take burning tics rapidly every ~0.5 seconds and this lasts until they die. Its impossible to heal through, and it doesn't go away after 2 or 3 'rounds'.
I fought the lighthouse ghoul, and he instagibbed himself in a similar fashion. He used the teleport attack over a patch of fire, and killed himself almost instantly to burn damage procs.
