[Known]Battle Error

[Yusei561 0]

During some battles this error message keeps popping up, is there some way to fix it? Also I noticed that in one case my Pokemon got defeated against a wild Pokemon and instead of letting me switch or run away from the battle the wild Pokemon just kept going with it's turn.
