So, as you all know (if you've done the antioch mission) if the person with the grenade explodes, your whole team dies. Well, that USED to happen until now. I found a way around it :P. Although, you cannot abuse it, it can save you if you're at a boss stage and the boss is at very little health. The glitch follows as:

Take out the crusaders you want to "survive" out of your current formation.
Once the antioch dies, quickly place them (the crusaders) back in the formation. (The highest I can put is 2. Try and do better dan dat)
The priests should be dead, but the crusaders should still do damage.
On the next stage, the priests should be alive again, and the crusaders should also be alive.
