My local game did also not have files in the behavior pack folder. I locally backed up the behavior pack folder from the server and deleted everything in the behavior pack golder(thinking if all else fails I can just put the copy back).
Restarted the server and bds reinstalled all the files for me.
Bug is gone generation is back to normal.
I also believe the files got corrupted in one of the updates.
