Thank You for the reply. However if you do want to fix your current world you need to find the seed your using.
Create a new world with that seed, fly around to the chunks you have your stuff at.
Create a nether potal and load in the nether.
Exit the game and go to the world saves and delete the world regions and replace them with the ones from the world you want repaired.
There you go. You also want to move over playerdata, advancments etc.
How do I fix this?
Yes it was
Also if an entity like a dog enters the portal the server crashes completly
I would like to close this. Turns out the ubuntu server is going into readonly mode due to other issues.
