Something Broke x2

Something happened during an update to WoW just now where it stopped at “Reclaiming Space” and went to a grey bar and said 98% updated. I don’t think I even clicked the update button to start this one. When I clicked the download icon to complete it the app said “Whoops something broke. Restart the app.” So I did and then there was no download to be seen.

I remember some time ago, I clicked update and got that error at 1% updated, and when I restarted the app it showed no update and I could just play. Could it have been continuing that update now?

I’m quite confused. Should I Scan and Repair?
