Enemy leaving "not dead" corpse when killed by thorns

Hello I noticed, when the charging mob (also known as petulant stonemaw) charges on you and dies from thorns during that charge he leaves behind his body model in standing (idle) position. That's usually only visual bug (which doesnt stop trial progression) except one time it bugged out right on place to socket soul orbs. I couldnt socket it back because bugged idle mob still had collision on. Also one time when rare petulant stonemaw died that way with some lighting damaging modifier it kept damaging me even after trial ended when I stood near body.

I'm guessing bug is very low priority since me and other 10 thorn mains are doing just fine, except that one time, which failed my trial.
