[1.7.4] Psionic / Voracity talents showing invalid numbers for Wanderer class

[Bananadine]

Just started a Higher Wanderer. My random categories were Combat Techniques, Stealth, Voracity, and Survival. The first three Voracity talents' descriptions don't make sense; they are showing me huge negative numbers and "not a number" values. But I guess the error disappears when I put a point into one of them.

This is due to those talents scaling with how much psi (percentage-wise) you have.
Before you learned one of them, you had no psi pool at all, making the talents very confused.
