Crash during pandemonium king fight

I used a pandemonium token and the pandemonium king appeared. I was just one attack from finishing the battle, i ordered my fallen carnage to attack, but a second after the damage appeared, the game showed a fatal error message and crashed.
Details: I was using a summon creature. It was the first time my siralim 2 crashed. I play on Android and my cell phone is a samsung galaxy s4. My android is v4.4. My siralim 2 is v2.1.2.
Sorry, I forgot to copy the error before closing the game… sorry, it’s the first time i report a bug. Sorry if i did/said anything wrong or didn’t do/say something important.
Did that happen to anyone else?
