I cannot get most of the upgrade rituals to work, I am certain I am doing it correctly.

The modifiers are not leveling up, as in showing the + sign after very extended use.

The Razor Edge modifier only applies to the inactive state of the tool.

I downloaded the newest version, which appeared to fix some of the issues,,,, sort of.

While the modifiers (sometimes) get a + sign, when i try to upgrade them to the next level, it thinks I am trying to apply the lvl 1 upgrade, preventing it from working.

Some of the modifiers don't appear to level up, specifically Quick Draw, after killing at least 50 zombies.
