I guess this is the best place to put this? anyway found a glitch/oversight in the multi battle targeting of Hau's Primarina, it ended up using hydro vortex on my pokemon (no animation for those curious) during one of the multi battles paired with him, (exact mechanics I'm not certain about, I think it was right after it used sparkiling aria on me when my pokemon was the only target, so I guess it didn't recheck for it's target but it could happen regardless of that I guess due to sparkling aria's range and no other data) I don't think it's going to matter very often due to presumably only affecting rowlet starters and needing primarina to get into the fight (and that possible other requirement, which is also uncomomn and likely restricts it to just this fight since it was 1-3 for the enemy pokemon amounts) and Even more uncommon of it would really causing a loss, but I thought I'd mention it for those interested in such things and so I don't forget about it without telling anyone.
