Endest Pearl Destroys/Prevents/Deletes Gravestones

FML. Possibly related to the fact that Corail did not register the death (no buffs, no key, no progress, etc.). /kill @a did form a grave stone. The endest pearl did damage through a full set of red matter gear, I don't know how to test given I'm teleported to world height, but possibly it deals void damage and this version of corail doesn't spawn a tombstone on death by void damage?
