I have just encountered the weirdest bug, ever.
Karma creation (did not doublecheck other modes)
My character is mystic-adept. I add a few points in MAG, I add a few powerpoints.
I merrily proceed to add adept powers...
So far, all working as it should.
I then add 'improved skill' and pick 'spellcasting' (because: why not) And suddenly, all my adept powers that have a rating (that is in my case only combat sense), drop to rating 0, and can not be raised.
I removed the improved spellcasting, and that didn't fix it.
I removed the other powers, re added them, and all worked well again, until I re add improved spellcasting.
Just 'for the lulz' I went to the skill tab to raise my spellcasting skill above 0, then tried again, and lo and behold, all is working as it should.
I assume this would be low priority as... who would use improved skill, without also raising the skill, but still... weeeeeeird. (and why does it affect other adept powers as well? I can sorta understand that there's a limit how much I can improve a skill with this, but... combat sense?)
Also just tried and checked, and this happens with ANY other skill (that I've tried, too many to try them ALL), as long as that skill is at rating 0 on the skills tab.
Edit: Even my 'Astral Perception' power was somehow knocked down to 0 by this bug, and that isn't even meant to have an adjustable rating.
