Errors: Exception while ticking neighbors and exception ticking world

I have a custom biome for a custom dimension, and everything functions as expected, but sometimes the chunks will stop loading at a certain point and then Minecraft crashes and Mcreator freezes. I have checked all of the crash logs, and it seems to be something to do with fluid movement/rendering, specifically lava. Does anyone know what this means and how I can fix it?

That crazy chunk of text duplicates for several hundred lines, then it repeats this a bunch of times:
