Dead withers not despawning
Hi, we have a server-wide griefing problem where players are building Withers immediately next to other players' claims. That alone is its own issue but the important one is that some of the ones we've killed recently are not despawning. They are dead, seemingly stuck in the death animation, but they persist through server restarts and furthermore they cannot be targeted by entity selectors. We have tried everything:
Screenshot shows what we're dealing with. The hitboxes are indeed the Wither entities, as middle-clicking them produces a Wither spawn egg, and yet as entities it is impossible to target them. Even when pushing the hitboxes away using pistons, the body of the mob remains stuck in place.
We are out of known options and desperately require a solution aside from regenerating the whole world. Please advise.
/minecraft:kill @e[type=wither]/butcherwith the-fflag/minecraft:data modify entity @n[type=wither]/mvpurge world WITHER- No command can target them, I've tried with the
distanceattribute as well. - They cannot be hit.
- They cannot be renamed.
- They are not affected by collision.
- They cannot be manipulated into riding minecarts.
- Pistons can push the hitboxes, but the corpse remains.
