	Yes. This effect has existed in all versions since 0.92.2. I 
	have been trying to hunt it down, but have not had much success.
	I agree that this is a severe bug. 

	Can you be more specific about how to make this bug appear? One
	of my problems with fixing this is that I can't usually get it to 
	happen.

	I did find one (minor) bug.. in SK_level. Basically, if a multi-square
	monster cast a spell from a non "head" square, the wrong value of
	the level would be inherited by the spell. I include a small,
	minor patch for this. NOTE: I have seen 1 hex spells cast by single-
	square creatures (ie beholder) so I DONT expect this is the root
	cause of the bug.

	Ill try to look into the teleporter bug. Can you recogmend a map
	which crashes often?
