I think I remember reading an instance of the bug one or two months back, so I guess it’s still not fixed. As for your particular case, I’m pretty darn sure that revisions are irrelevant in regards to lateness. I cannot even remember the last time I saw that bold red LATE text, so I’m not the best to talk out of personal experience, but I’ve read of orders that have stayed in revision for MONTHS, eventually closed after a seemingly unending ping pong match between buyer and seller, and the order still not being considered late.
