While doing a Randomizer nuzlocke, my first fight with Damian after we got our pokemon, he got Hoopa, which Destiny knotted. Fight ended with him "losing" but my pokemon fainting. I got the winning text and did not go to the pokemon center, but my only pokemon was still fainted. Still couldn't revive it at the pokemon center, because nuzlocke and all. I finally crashed when I first started a battle. The error message was something like "no unfainted pokemon"
Posting this as a blocker because it ends everything in the Randomizer Nuzlocke I was doing.
