Festival Ground (TWM #149) - Pokemon Not Recovering from Special Conditions

Pokémon Charizard ex (OBF #125) was put into play, and energies were attached using the ability "Infernal Reign". Next turn, opposing Pokémon Munkidori (TWM #95). For next few turns my Charizard ex made multiple attempts to attack (some successful with heads, some unsuccessful with tails). The opponent then played Festival Grounds into play.

The Festival Grounds text appeared on the screen, and the card flashed big on the screen like it was going to do something, but the Charizard was not healed from the confusion.

For the rest of the game after every action that each player took, the Festival Grounds text appeared on the screen, and the card flashed big twice, but the Charizard never recovered from the confusion. (This behaviour is shown in the YT short linked below.)

This occurred after every action that each player made for the rest of the game, until the Charizard ex was removed from pay using Processor Turo's Scenario (PAR #171)
