Critical Mastery feat - prerequisites

[Nalgaeryn]

Hey, I'm not sure if this is an issue with TTT or with the base game.

If you take Critical Focus (feat gives +4 to crit confirmation rolls) then you can take a whole selection of other feats: Sickening Critical Tiring Critical Bleeding Critical Blinding Critical Stunning Critical Exhausting Critical Staggering Critical Flaying Critical*

All of those feats say: "Special: You can only apply the effects of one critical feat to a given critical hit unless you possess Critical Mastery."

You need to take two of these feats to get any bonus from Critical Mastery. It has the following prerequisites:

Critical Focus Fighter level 14 and TWO OF:

• Blinding Critical
• Exhausting Critical
• Sickening Critical
• Staggering Critical
• Tiring Critical

For some reason, Bleeding, Stunning, and Flaying don't let you qualify for this feat, even though they have the caveat included in their description.

Is this a base game issue, or an issue with another mod that added these feats and didn't integrate them fully?

This looks like another mod adding new critical feats but not updating the critical mastery prerequisites
