Please help!

There are several artifacts challenges (7.x) to get on Castle Kaerok, but the game is extremely instable there!

We can run one or twice, three times with luck then it crashes and exit the game.

This ONLY happens on Kaeroks stages (any of them!), but not in other Campaign places or other battle areas.

Please help! it's very compromising progress and interest on play!

Thanks in advance
