Boomer/Headless Horseman glitch

If you attack a boomer and don't kill it is supposed to spawn another boomer. However, due to a glitch it is spawning Headless Horsemen called "Boomer". Keep in mind the glitched Headless Horseman does not yield any exp however it always drops 5 Tynerum Shards so if you want those for some reason knock yourself out.

If you don't believe me either check for yourself or go to SouthPerry and find the recent extractions and open up the Mob (Changed) 111-120 tab.
