Potential Fix for “Wither Storm Doesn’t Die” Bug

I ran into this exact issue while playing with friends on an IzzelAliz Arclight 1.20.1 server. After we destroyed the command block, the Wither Storm stayed alive and the fight never ended.

At first, I tried killing it directly with commands using its UUID — no luck. Then I tested the same world on a clean Forge server and found a workaround:

What worked for me (multiplayer case):

1. Set up a clean Forge 1.20.1 server.
2. Copied my bugged world folder from the Arclight server into the Forge server directory.
3. Inside that world folder, deleted the dimensions folder (this contains the Wither Storm’s bowels dimension).
4. Started the Forge server with this modified world.
5. Joined, re-fought the Wither Storm, and it finally died as expected — fight ended normally.

Why this works:
The dimensions folder reset seems to clear the bowels dimension and the fight state, allowing the final kill to register.

Workaround for singleplayer players:

1. Create a new singleplayer world in the same Minecraft version.
2. Exit the game.
3. Replace the new world’s folder with your bugged world folder.
4. Inside that folder, delete the dimensions directory.
5. Load the singleplayer world — the Wither Storm fight will reset and should work normally.

this is just a guess but the witherstorm should be in phase seven when you kill the command block not phase 3 maybe that has something to do with it?

What texture pack do you have on?

Update:
Apparently the reason why the command block isn't dying is that its health is getting set to NaN, IDK why
(No, it has nothing to do with the wither storm's phase)

Still getting this bug on the latest version
