[UNSOLVED]World Generation Issues

My current goal is to have the main world "world1" be a loading area and "world2" be an arena world which regenerates after every round of the game. However, using my current methods whenever I regen all the chunks in world2 after deleting the old world and recreatign it, the biomes become all messed up and water seems to hang in the area randomly. How can I fix this issue?

All these 502 errors caused me to post this in the wrong forum, could mod please move?
