changed description "Clicking on the Shuffle button multiple times while it's mid-execution duplicates the entire Stack a number of times consistent with the number of clicks. I noticed this today after pulling a bunch of tracks for the day. I clicked the shuffle button like I tend to click save on things and ended up with 3 copies of each song in my stack, cleared the duplicates from my stack, then refreshed and tried it again, same results. Potentially related, the track count in the stack seems to fluctuate wildly and inconsistently during this process, often landing on an inacurrate count. Steps to reproduce: add tracks to stack, click shuffle & while it's flashing to indicate action, click on it some more I'm seeing this in Chrome on Windows 10 fwiw. * as a mild update after submitting this, every time I click shuffle at all now, it duplicates my stack ~55 times. I had 19 in there, clicked shuffle, and now have 1045."
