Can I update my UEFN map made for the MegaJam?

I was unable to test my game with multiple players before releasing for the MegaJam. It turns out that I should have allocated score differently with multiple players in the game. (the way score math works, when you assign the same amount of score to multiple players at once using a score device, it only gives the team the score amount, rather than multiplying the score amount) Because it’s a MegaJam game, I’m not supposed to update it. However, I am currently in Discover and have a bunch of players wandering around my game unable to finish a round.

Can I fix this without breaking the rules of the jam?
