When a character receives multiple Insight bonuses they are stacking instead of taking the highest value.
This can be replicated by creating a Mechanic, selecting Exocortex, adding 1 rank to Computers or Engineering, then taking Skill Focus (from Exocotex) for either Computers or Engineering. The resulting bonus is +7 when it should be +6. The extra +1 seems to be coming from the Bypass class ability.
There seems to be no data file errors that I could find.
