I had looked for a while for a way to delete corrupt chunks. I'm not a computer programmer, but within an hour I watched a short online video by PythonMC, downloaded NBTExplorer, and deleted the corrupt chunks from my world. Thank you John Spanos and others!
I meant the default profiles....

How is this issue not resolved yet? It occurred due to an update months ago prior to us moving. We have moved and settled in and still can’t play our characters on our Realm with split screen.
