Nope. Nobody. Ever. ;) Seriously though, you posted yesterday at 8:55am and asked for a follow-up less than 26hrs later... during Miami Music Week! We're working hard to get to all the posts here and in our ticket system, of which there are hundreds every day, during one of the busiest weeks of the year for our team, so if we took more than 24 hours, our apologies.
To answer your question...
If you are re-analysing tracks, my question is ... why? If they've already been analysed and had their beat grids adjusted, why are you scanning them again? If you want to do the entire library but not lose the work you've already performed, consider locking the tracks instead. Select the one(s) you want to lock, right-click and select Analysis Lock > On.
