Error in Imp affecting call monster sprite

Well the easiest fix is removing the patche(s) that cause this problem. Testing if the game doesn't crash is a good start but it doesn't mean there won't be more problem. You may also have a patch conflict that use the same free space and this is the result. I would inform leetsketcher when you find the culprit..

Found the problem in using V1.0 us rom. If I apply Leet's Imp Skimp & Unaffected Rows from http://assassin17.brinkster.net/, then undead sprite is corrupted. 

So I just need to unpatch one of them.
