Simultaneous KO at Jade Tower East plot battle, walking with all-fainted team

[Nikita Colletta]

While facing East for the Jade Tower plot battle, his Talonflame (last Pokemon) KO'd my Delta-Charizard (last Pokemon) with a priority Brave Bird, but the Talonflame fainted the same turn from the recoil damage resulting in a hilarious tie for the scenario.

The following cut-scene counted me as winning, and I'm currently walking around with all my Pokemon at 0HP (fainted). Haven't attempted to move to the next room yet, attached a screencap of the all fainted team to vouch.

Ignored the Chansey because was curious to see what happened in the next battle. Notice the Pokeballs xvx;

When trying to send a Pokemon out in battle it crashed. Crash log attached. I saved in the Chansey room beforehand, the game starts up fine with a still all fainted Pokemon. Game plays fine afterwards.
