So it would seem, this version of the server no longer loads, I don't know why, it was working for a long time but when this update came out it just stopped loading.

I checked the bug tracker and it looks like others were having the same problem, one person even reported it happened on Windows 10,
I'm using Ubuntu for this software. This is very strange, if somebody else has a solution I will kindly accept the help.

Right now all I can do is wait for the next update and hope it gets fixed,
I figure putting the file on a realm could cause more trouble and potentially corrupt the file,
Plus I don't like using realms because they have an awful render distance that does affect gameplay not just graphics,
it affects whether or not you can see outer islands in End and what biomes are ahead of you in Overworld.

It's not too much of an issue in the Nether, because of all the fog that masks distant objects or mobs.
But having a low render distance kills the experience in the other dimensions,

So I'd like to be able to get my custom server working again.
