Upon entering the nether and performing a lot of work, Left nether for a while and came back. Upon reentry was placed in a random location in the nether nowhere near the coordinates it should be, With NO portal. walked back to the location of the original portal to find all the work gone and no portal. Had to go into creative to build a portal to get out. Every time any work is done in the nether, upon reentry its all gone and reverted to original nether. Also on side note, Lava without source block
-Only one nether portal open in the server
-Server settings besides ram usage have not been modified
Happens WITHOUT a reboot while still live

This appears to be the whole nether though, along with the portal, also nothing happening wrong happening in the overworld except the map bug. So I don't know if its the same issue, neither has there been a crash.

After having this issue:
Please attach the complete output of the "Game Output (Your Minecraft name) " which can be found on the fourth tab of the launcher.
If the launcher closes after game start, please edit your profile and select "Launcher visibility" then, "Keep the launcher open".

I did mention this was a server right? Do you want the server logs?

So this happens EVERY exit/reentry to the nether. Portal has been deleted and regenerated in new areas with some of the work deleted most of the time and once in a while all of it deleted. Pictures are in order of events, I did a little bit of work and then left and came back. Nothing was removed only added and as you can see the last one decided to move the portal and delete everything. Server log to follow
