So, I was using my skeleton spawners that I have built in my base, when a stacked skeleton glitched into the Death state, rendering it invulnerable, and skeletons that now spawn stack into it.
This is fixable by the player, as they would only need to despawn the mob (as any mob stacking will potentially trigger this), but that does not mean it isn't annoying, or potentially catastrophic.
