Map has issues loading (Solved)

[nuggpuffer]

So i have a strange issue, my world has a spot in it where the map just doesnt load correctly and when i enter it, the game crashes. this only happens in a multiplayer world, in single player i can enter it just fine. It happens in multiplayer even when im playing alone, but it fixes itself when im playing solo and allows me to pass through just fine hence why there are torches.


So after quite some time trouble shooting it turned out to be the mod Structure Helper trying to overwrite another world gen. mod and therefore causing a world gen bug, after disabling that mod it fixed the issue.
