End island(s) is/are screwed up.
The end fountain spawned inside the void, causing there to be no portals after we killed the dragon.
We are now stuck in the end forever as this issue occurred in hardcore mode.
I cannot control weird snapshot version, as this is not my server.
We had to delete this save and start over, as we could not leave the end.
Thank you for your report!
