Heya, I have just uploaded a pre-early version of v0.26 for Windows which might fix the buff issue!
Buffs previously did not update to account for changes when they are leveled up and recast by auto buff. For now, pressing [ESC] then [Quicksave] and then exiting to menu and continuing should fix this on v0.25.
I will check out the belt stats on my side!
Edit: FOUND the issue! Belts will properly apply in v0.26 , re-uploading v0.26 with the fix for belts now! I am so grateful for the details!
THANK YOU SO MUCH FOR BRINGING THESE TO MY ATTENTION! <3
