Delwyn blocking exits after successful spirit run

Hi!

Delwyn has an annoying habit of block narrow pathways after you kill the target of the spirit. Sometimes you can roll past him, sometimes you cannot :(. Is it possible to make him either move around at times so he unblocks the path, or make him pass through after the spirit event is completed?

+1 make Delwyn himself a spirit so I can walk through him when he's blocking a narrow path.
