Coin system

You owe me coins.... lol. I guess this is the lastest bug in the game. I had a Pokémon in a gym.., was there for almost 4 days.. once it was knocked out I never received any coins, 8 hours later still nothing. I had another Pokémon in for 2 days at another gym and received coins immediately. Whats up with that? Lol I have another one whos been in a gym for 12 days... should I expect no coins? lol
