My game crashes whenever I use Tsunami or Virulent Gust

Today my game crashed multiple times after using one of the two moves mentioned above, instantly kicking me from the game. If I don't use one of those two moves and I finish the battle in any other way I get the connection error and I have to refresh the game. The only thing that came to my mind was to verify the integrity of the game files, but that hasn't fixed it... is anyone else having this issue or a similar one?
