Grand hall trainer skipping turns ( very specific conditions)

[missdragoon 0]

At the grand hall after you return to the city one of the grand hall trainer has a funny little glitch. 

I've only seen it with a water pulsing clawitzer so far but this trainer (see screenshot)

She will skip turns with her Male Meowstic after putting up a lightscreen 

So far this has only happened when : 
1. it outspeeds my clawitzer and gets to put up a lightscreen ( it always does this first) ,
2 it doesn't happen with reflect or any of its other moves.
3.Any other mon I put up front doesn't trigger this either as the battle goes on as it should. 
4.Its only the Meowstic that has shown this behaviour and only when its up against the Clawitzer
5.It skips its turn regardless of what move I use with the Clawitzer ( I tried surf, waterpulse, sludge wave and aura sphere)
6. After the meowstic has fainted the battle continues as normal without any issue's. 
7. edit: If i switch out to any other mon on my party battle continues as normal with the Meowstic actually taking turns.

Thats pretty much everything i've been able to get from this, its a really small bug but for some reason it was hilarious to me xD

Male meowstic gets prankster, so it has 1/3 chance of getting that ability. It sets up light screen with priority when it does.

However, I don't know much from your post whether it's that your turn is getting skipped or it's the meowstic's turn.

If it's the meowstic's turn, there's a chance that it goes like this:

- M sets light screen with prankster

- You attack

- You attack again because M chose an attacking move so it no longer outspeeds you

- M either attacks or faints this turn

Its his turn he skips, and he continously skips it untill he dies pretty much. Should problably have been a little clearer on that sorry but it goes something like this: 

Both trainer send out their mons: 

 

- Meowstic sets up light screen

- I attack with whatever move

- he skips his turn

- I go again

- he skips his turn.

 

And so on untill I either switch or straight up knock it out. Ive stalled it out for 8 turns and he just doesn't do anything at all after the light screen ( 8 turns is the longest I can skip it without killing it if im not using items)
