I swore I would never buy gems, but I broke down and did it. I purchased a bunch of mix and match challenges. Now for the stupid question. Can I activate more than one of them at a time? I am working on a time consuming one and want a break. I just don't want to lose the progress I have made so far.
Unfortunately, you can only do one at a time.
Thank you. Told ya it was a stupid question. lol
