I have been trying to update a mod from 1.16.5 (Shadowlands) to 1.18.2. No errors show when compiling, however on trying to create a world it shows an error screen saying it failed to load datapacks. I'm using Mcreator version 2022.1

Error screen:



clicking "safe mode" does nothing.

It sounds like something is wrong with the Shadowbraxis dimension, although I have no idea what or how to fix it.

Code of dimension: https://pastebin.com/tyDa2Ezw

it works fine in 1.16.5.

[​edit] seems to only happen when the dimension is set to have more than one modded biome, which is odd since it's only a problem for that dimension.

[​edit 2] Right so I've found what the problem was - biomes cannot have very high biome weights. I don't know what the limit is but 300 seems to be way too high, I changed it to 10 for all the biomes in the dimension and it works now.
