custom dimension not allowing more than one biome without crash (updated fixed!)

(note mod is not set as a datapack and is indeed a forge mod)

so went to add a second biome to my dimention and when i go to test it "errors in current datapack prevented world from loading" and this is not a datapack its a forge mod! and i have no other mods in to conflict with mine, i need help ASAP as this error is really getting on my nerves lol and needs to be fixed before 2022.3

other than that everything else seems to work good

the fix is the biome weight to be all even numbers for some reason! but it works now!
