World seams / seed change on server restart (1.9 + 1.10) #444
Just wanted to officially report this as a bug here on the bug tracker. Some more details in the links below:
I can confirm that there is no error in the log concerning level.dat corruption (as first suggested by rutger).
The bug is easily reproduced by loading up Biome Bundle in Spigot 1.9/.1.10 as it happens every time the server is restarted. (if doing so be sure to change population bounds check to false to stop the tripwire bug crashing things).
After more testing of workarounds for this issue it has been discovered that specifying a seed in server.properties seems to prevent it. Hope that helps in narrowing down the cause :)
Edit: Actually, it does not seem to prevent it entirely I still have some users reporting it.
Thank you very much, that narrows down the search considerably. All changes between 120 and 115 are:
If I just look at this, I would guess it has something to do with ReplaceToBiomeName... That's not at all where I expected the bug to be.
