If you kill an enemy and the knockback goes off, it pushes everything on the floor back to where the enemy would have been knocked back to, corpses, items and all. Unfortunately this includes the Satanic Displacement Gylphs. If you enter one that has been moved, it takes you to the correct corresponding glyph, and re-entering that one will take you to the spot that the original glyph once inhabited. In other words, it will teleport you to a spot just a few squares from where you entered the original. Not a huge deal, just thought maybe the glyphs should be immovable. Also, sorry if this has already been mentioned.
