Title says it all. Since Necrom, unless I slow my key presses in a dungeon fight, when the fight is over and time to loot I can't - I can't interact using "E" with environment at all.
Logging out and back in restores the ability to use "E" to interact.
If I slow my key presses during the fight I can still use "E" after a dungeon fight.
I really haven't tested this in overland as I haven't been playing the game much since Necrom for some reason.
I suppose I could adopt a heavy attack build to accommodate whatever bug you introduced with Necrom.
