Just wanted to warn everyone that in the Nether farm world somewhere close to the spawn point, someone spawned a wither. it’s under a lava lake but is able to shoot through. It also can break through blocks. I lost all my stuff after I was mining quartz by the lake and it broke a wall holding back lava. Just thought I’d let everyone know about it.
Thanks for the warning! We will probably just reset the farm world. It’s been a while.
Can i try to kill the wither?
World has been reset! 
The wither should be gone.
Awesome, thanks! Will the end world be reset too?
Yes! We always reset all farm world’s at once.
