This gives me a lot to look at to find the softlocks being reported by people; the next level starting is dependent on both all enemy ships being freed (happens when they exit the screen or get shot) as well as all the salvage being freed (also when it exits the screen or gets picked up). I'm thinking the softlock is salvage spawning within the screen-edge areas and never being freed, though their autostart timers should be solving that. I appreciate the feedback, thanks for playing!
