Hello, I just discovered when 2 trainers are very close like that you can skip the second trainer just by pressing Space Bar plus the arrow, and you'll move a little while they speak, so when the battle is over you'll be 1 or 2 steps away.

 

 

I don't know if this is a bug or not, but I thought I should post it.

 

Thanks for your time.

Hello there,

That happens sometimes if your connection doesn't sync well with the server. However, you don't have to worry as it's not a big issue and won't really affect your gameplay. Thank you for reporting this anyways, hope you have a nice day~
