I have a character with access to the Transformation skill via a fabrial. When I had no ranks in the Transformation skill, everything worked correctly. But after I took a rank in Transformation, the modifier disappeared:
Great catch. I wanted to see if it occurred with the other surges, so I made a copy of your character. However I couldn’t replicate the issue on Chrome 140.0.7339.81.
I hadn’t thought to include my browser in my reports, great point. You’ve inspired me to report some Fabrial issues I’ve found, so I’ll include it in my reports
Edit: I’ve been able to replicate the issue! It might be a coincidence but for me it occurred when the modified Surge Skill matched my Willpower attribute. It’s like the algorithm didn’t know which to choose when they were equal, so it chose neither.
