Hmm, that icon is a core asset to the game (borrowed from Meltdown). The path you mentioned to the icon isn’t located in the mod, it’s core game location. I’ll take another look at it and re-upload it, but you might try to have Steam inspect files.

The mod works properly overall; however, I noticed that in version 1.01-241, the icon image is missing from the path Icon = "UI/Icons/Perks/VengefulTemperament". Simply adding the image to that location should make the icon display correctly. Cheers!
