How does one solve a tempo crisis?
after it's already happened, there's probably not much you can do. find a compromise tempo that's half way in between the right tempo for either part. but if it's too severe, you might look into some kind of tempo change in the song, but i think this usually doesn't work. and the 3rd option is to file the 2 sections separately into 2 different songs and continue with one of them. but to prevent a tempo crisis, get a metronome going early on. pause it to think, but when testing out ideas and doing runthroughs, always do it on click. can't go wrong that way
