This is a bit niche and probably not high on the list of priorities, but I figured I’d note it here for when the team have time for a quick fix.
Big Wheel’s Tread on Me power can’t be fired if you can’t target an enemy. Given that the power doesn’t just do damage but also does board manipulation, this is a little annoying. I was trying to use to match an invisibility tile so that I could then target the enemy with other powers.
