So I fixed rooter in beta4 but the meteor shower is still happening. I thought there was something I was missing and was just stuck. Just came back to it today and found this thread. I guess I'll reload from before fixing rooter.
Edit: Apparently that save was corrupted. It played the meteor cutscene every time I re-entered the scrapyard. I had another save from when I'd just came down the elevator (instead of coming in from the scrapyard with rooter after the meteorite cutscene) which worked fine (once I'd entered the scrapyard a second time the meotorite showed up).
