Skillups with Attack on on corpses
 

Level 17 rogue, in bottom of unrest. killed a mob, couldn't target it. assisted off other player who could target corpse, then started getting skillups from the targeted corpse! skillups like dual wield, double attack, etc. I still could not loot corpse (got message about corpse being too far away), yet constantly got skillups till they topped out.

Very weird and not good.

P.S. I changed weapons and the skillups stopped. Not sure if I can duplicate, but will continue to investigate.
