I tried to update Botania to r1.9-328, but when the game is loading, the menu loads but i can't click on anything, it do not crash, just stuck
It is working just fine with version r1.9-326

I can't reproduce this. You'll need to do some testing to see if you can determine whether another mod causes it.
