Audio glitches when rack power turned off
I'm working on a multitrack recording trying to turn it into a final mix. I'm basically done with the editing and mixing, and am trying to export the final mixdown. I'm having a weird issue where whenever the rack power is off on one of my vocal master buses, a constant audio glitch covers both the left and right output tracks. The same occurs if I use the rack mix and set it to 0 (completely dry). It's not the effects in the rack, as it does this even when all the effects are powered off. This bug only appeared after updating to CC 2018. After reinstalling Audition CC2017, I also notice that the mixdown takes about 45 seconds in 2017, and only 15-20 in 2018. That might be something, or it might not.
I've uploaded a sample of the bug to Dropbox. The rack is off for the the first part of the clip and on for the second. Careful, the glitch is really loud.
