[Answered] Why is Psi Skill in the save negative?

[Morbo]

Hi, not sure if it's specifically related to OXE+ or not, but thought I'd start here:

version: Extended+ 3.9c
build: " (v2017-10-10)"

I have Psi training anytime turned on, but just started training so no one has actual psiskill yet.
When i check the save game file, their psiskill has a negative number.

What does the negative number mean for psiskill?

Negative number means number of days until the initial training/screening is complete.
