About this Mod
The Birch Allergy Mod:
This mod adds crucial changes to minecraft, including but not limited to making birch even worse, in order to make sure that no one ever uses it, making important and long needed changes to the speed of minecarts, and changing the generation of minecraft's trees.
Our motivation to make this mod mainly comes from the youtuber camman18, who always had the objective opinion, that the speed of minecarts was too low.
This mod may be incompatibel with other structure-revamp or terrain mods!
Next planned Update:
Birch Boss and more !
