I was able to figure out that it had to do with reply threading not being properly imported, which may have had to do with the fact that reply threads weren’t enabled on the bbPress end at the time of import. So the newest reply would show up in the middle of the thread, because all of the replies that after that one were I guess orphaned replies to previous ones.
I was able to solve this by manually editing each of the replies and setting its parent. I think that threads that began after the import, as well as threads that have not been replied to since the import won’t be affected, only the ones that were active before and after. So I’ll monitor the forums and fix the reply hierarchy of any resurrected threads
