Well, I think this is still better than relying on chance and replaying. Even though you won't gain experience, the troops will be lost fairly. Otherwise, you could replay, and luck might be distributed differently, and resistance might work differently, and a unicorn might blind someone, and a dragon's foresight might age someone... and one gremlin might die and not plug the hole in the wall...

Well, if you like this option, go for it, but make sure to take a screenshot, and also keep track of how much mana everyone has left and how many spells they can still cast – this is quite a hassle, to be honest.... That's why, for me personally, it's easier to replay from the beginning than to deal with dismissing troops and artificially positioning them on the battlefield!

P.S.: For some reason, I immediately understood that you were playing with Save Editor. This is the second time a controversial situation has arisen. You are absolutely not meant to play against each other :D
