My Mix checks are probably easy enough to work around. Gleam Sand should be allowed, I'll go through and add the check for that.
Adding loadouts to the Normal and Hard challenges would be a good idea. I could probably reuse some of the code, too.
Did the Lifespark heal the Lanterngeist? The check gets the HP the Lanterngeist was at before the attack hit, so maybe the Lifespark used Power Pool.
Not sure off the top of my head what caused the big bug- maybe Fire related, but likely because Brill got KO'd after the fight. But now's probably a good time for me to go through "timed attack" effects like Volley (and Artillery Fire) and add a check that keeps them from activating if the enemies are all KO'd. (I'll keep it on Echo Tonics because that's useful.) I'll get on that after I've finished up with work.
