He fixed things to get the missing communities back, but it looks like subsequent runs of the crawler lost them again, so now it’s rejecting updates because the difference is too great (it always used to do this, so I don’t know how it was publishing with so many missing before).

Anyway, it looks like I’m going to have to do the most NSFW imaginable - look at someone else’s TypeScript project. I’ll get back in touch with him if it doesn’t correct itself, but it’ll be nice if I can figure out what the problem is first.
