Everyone else was just in a block download initialization . So you guys started creating your own chain with no one else there to tell it was not right.  Again I suspect when the fork started up, many clients struggled due to many blocks to quickly, you got caught up on that. I think a fresh re-sync form the last good backup should be good.
