[Known] Double battle Dragon Tail

[Elvenlore 37]

I did a quick search to see if this had come up before but couldn't find anything, so figured I'd post it.

 

In-game, I reached the point where I team up with Aya and get separated from Hardy and Cain. We're travelling through the mountain and encounter a wild Kangaskhan and Druddigon (My Donphan and Aya's Druddigon vs wild Kangaskhan and Druddigon). Kangaskhan faints after taking damage. Druddigon uses Dragon Tail on my Donphan -- which should force a switch -- but Donphan's sprite merely disappeared and the next turn started as "normal" with Aya's Dragalge and a now invisible Donphan. No switch forced.

 

I don't know if this happens with other switch-forcing moves.

 

Edit: ...And I'm not sure if I saw that wrong but I think Aya just moved twice in one turn.
