Update: Rolled check without Guidance and it got one point above success roll. It actually gave me the success roll to the Insight check. I am not sure if this was due to it being so close to the success roll or there not being guidance casted on the character (custom character) at the time of the check. It may be due to the Guidance bugging the check or it might be rolling too high of a roll means failure. Not sure. Just thought I would report my findings.
