Akithweh corpse thrall interaction

Expected: Akith'weh's corpse thrall would respect servitor affiliation for wall of putrid flesh as it does for zombies and similar. Actual: Akith'weh will hit your own wall of putrid flesh, which in turn causes it to unfollow you and aggro you in certain situations. Looks like its just not accounted for? Steps to reproduce: 1. Go to a graveyard with the Akith'weh greater undead. 2. Put up wall of putrid flesh. 3. Fight something relatively tough so it doesn't just die. 4. When the Akith'weh corpse thralls, it will hit your wall of putrid flesh. 5. Remove the target immediately (fleeing for example if a player). Death might not work. 6. If the target leaves before the next round, the Akith'weh will aggro the controlling necromancer.
