I created this mod mostly out of laziness, as I couldn't find a way to make a working mob trap in 1.20, but thought others may find this nice to have.

This mod should hopefully remove the new Shiver and Bowtorn mobs from the temporal storm spawn pool, this wont prevent any natural spawns for the Bowtorn or Shiver, if they can occur during the storm, but all storm types have had their weights and spawn chances modified to hopefully make storms Drifter only.

I've some testing, but there may be issues that I've missed, if you find any please comment and I'll try to fix them asap!
(there's also a chance that this is reducing the mob spawns during temporal storms but I might just be imagining things, if someone else notices this please let me know lol)
