Hello!

These lines lead me to believe that boania is an optional dependency

but ModTweaks runs botania related code even if the mod isn't present:

Leading to this crash report: https://gist.github.com/Ephys/7d647142970b6845076cf939367fe994

I do have some checks for if Botania is loaded or not, perhaps it's not checking it very well. Will have a look later.
