Before 1.18, the brushes all showed a materia cost for different blocks/items, but now there's nothing, it says that I need to have the block on me to use the spell. Now I'm stuck with excess materia that isn't being used at all :(

Sorry, I completely missed this issue- is it still a problem? As far as I know, the materia system is working.

This seems like it got fixed, please let me know if you're still having issues.
