Hello, thank you for pointing this out.
I'll move this to the proper section, as this might indeed be a bug in the battle system, will be tested as soon as possible.
Just to make sure I'll be able to replicate the eventual bug:
1. You were waiting for the player to make a move, not being afk.
2. When the timer ended, the battle didn't result in a win for you, instead you ended up both disconnected.
Can you confirm that is what happened?
