[E17] [Enemy Inaction] Truant causes the Happiny AI not to take a move

[IntSys 106]

Format: Singles
Slakoth (Player's) vs Happiny (Enemy's)
Field Effect: None
Opponent: Arcade Star Eilee (The trainer next to Silph Co., in Obsidia Ward)
Slakoth's Ability: Truant
Slakoth's Move: Feint Attack
Note: Slakoth's faster.

Turn 1: Slakoth uses Feint Attack. Happiny then uses Sweet Kiss, but misses.
Turn 2: Slakoth truants. Happiny does not take a move.
Turn 3: Slakoth uses Feint Attack and finishes Happiny off.

Tried it again, with Sweet Kiss hitting, but the rest is still the same.

I've also experimented it on other trainers, and it seems that Truant does not cause them not to take a move.
