Does a short video demonstrating the issue help Sitra? I can upload the log as well if you like. What I do for testing the flanking issue: Start a new game, create a bard and someone else, level the bard to level 2 spawn a gnoll, set fudge dice rolls to 1. Start combat, I hit two rounds with both combatants (of course they always miss) but I can see the +2 flanking bonus. As soon as I start to change this setup by casting a spell that adds a condition like undersong, which isn't even combat related, I start not getting the flanking bonus nor do I provoke AoO with the bard, if I start moving around the gnoll. EDIT: I took a short video for demonstration purpose, though I forgot to demonstrate the AoO issue in the clip.
