Edit: Re-read the FAQ and discovered this is due to high courage stats, not a glitch as I originally thought. This can be deleted.

One of my pumas has an extra version of the same tactic. When I go to change his tactics he has two chances for "attack", but it's the same simple version, not a special one. I checked the tactic FAQ and he doesn't have anything that should grant him that extra. He has got Lionheart, but that isn't listed in the FAQ as granting anything special. Here's the pet in question: click, and I've attached a screenshot of the extra option. I'm not entirely sure this is a glitch, but I don't want to put him in a squad until I discover whether this is really something he's supposed to have.
