Rise of the empire special mission: Mandalore fail

I just had a double eat/sprayed happen to me and I do not understand how this is allowed to happen.

it makes it so I have zero chance to actually do the special mission. It’s almost an instant fail.

the Krayt dragon should NOT be able to eat and then instantly spray. And definitely not able to do it again after I got one attack in. 
normally my team clears this with no issue. I’ve worked hard to have high relic and well modded team and I know the battle.

This is a failure of the mission not anything skill related. Why not just give us random instant fails instead? It would at least be more clear that fairness and skill don’t matter in this special mission. Fix this **bleep**
