Compare bug report.zip (3.5 MB) This is my first bug report so please bear with me if this is done in a bad way.
So when I’m comparing a wand in the forge with my currently equipped one by holding ctrl, the mana from the affix “spell damage and mana cost” doesn’t show the “-3 mana cost” part.
I have attached two screenshots in the zip as well.
I’m running windows 10 19041 and I guess you can find hardware information in the attached files. If anything is missing, I will of course provide the missing information.
Edit: Sorry but I have tried to get these pictures to show correctly for some time now and nothing seems to work. They are also in the zip if you don’t see them.

A very happy player in general. 
Good job on the game.
