Hi there! Glad you’re having a good time :)
There should already be a “retry” option that pops up on a combat loss that replays the mission from the Lancers’ starting values. Are you seeing that // is it not currently working? It sounds like the difference between it and what you have in mind is it popping you back out of combat to the beat instead of just the start of combat. Am I understanding correctly?
If that doesn’t fit your needs, I can see if I can add a trigger that sets a unit’s values from something stashed in Combat/Module State so you can do it manually.
