Stun not working?

Mischabäst

After the last maintenance I’ve had some issues with the game. One of them is that I can’t connect stuns and today I could not get any stuns at all in master last chapter. And that’s strange because my team was Bw Hulk Hyperion Thor and quake. And no stuns. Zero. And with those synergies it should be stun almost every time. So I’m wondering if anyone else had stun problems?
