I mean: when the rebels made all the objs, and the map doesnt restart.
I think when rebels get two or more droid parts at the same time to the falcon the game crushes in a way, so it doesnt know the objs are done. I saw this two time, so it's not sure but it looks like.
Maybe this was explored by someone elso before, i dont know, i searched to this but didnt find anything, but if it was sorry for repost!
