Gym bug

Either its the games system or these are spoofers,
Keep on getting "network error" while or before barreling in this specific gym.
Sometimes I defeat the Blissy in the gym and the game gets stuck on the battle screen with Blissy with no health but not fainted, sometimes my Pokémon die and Im thrown out of the gym without even barreling?!
