i was trying to make primitive mobs rare by using addrarity thing, but changing it at all seems to cause it to crash the second it tries to load

crash log: https://justpaste.it/5zpx3

...also hello again Davey, i really enjoy what i have seen so far but man this mod does not like me.

Are you using the latest version? (1.0.5) that one SHOULD fix negative values being an issue; otherwise did you accidently add a negative value aside from -1 to the additional rarity stuff?

it's not just negatives, i tried making all positives or zeros and it still crashed, and the file that i have in my mod folder says 1.0.5, but i did notice in the options in game it says it was the previous version (1.0.4a)

update: after changing somethings around, it seems to not like zero, as setting everything above it lets it work, but the problem is still there so ill keep this open for now.
