Audio Quantize timing isse?

So I’ve used audio quantize (from the toolbar) 1/16th on an acoustic guitar track. Play it back and after a minute of playback, the track suddenly goes gradually out of time with the metronome. Yet when I stop playback and position the cursor to the out of time portion, it plays back perfectly in time again?

Has anyone else had this problem and is there a fix?

Am I the only person with this problem with Variaudio?

Anyone?
