Hi,
I have just updated your mod from 0.2.4 to 0.3.3 (only your mod), and now i get the message below.
I have the Corrundum mod installed but not Muluna.
Reverting to 0.2.4 fixes the error.
I would greatly appreciate a fix.
Thank you for the nice mod.

Error message.
Failed to load mods: harder-pack/compat/corrundum.lua:1: attempt to index global 'Muluna' (a nil value)
stack traceback:
harder-pack/compat/corrundum.lua:1: in main chunk
[C]: in function 'require'
harder-pack/data.lua:16: in main chunk

Forgot to delete a line from back when compats were handled in a different way, this line didn't even do anything in compat/corrundum ...

it has been removed, so the mod and it's compat should work with Corrundum even without Muluna.
