Red and Blue power went down mysteriously
A while back I won carnival hats for Red and Blue which boosted their levels up to about 24 and 27, respectively (I just started playing). Recently their power levels went down to about 18 and 20 and I can't figure out why. Both are still using their carnival hats. The only thing that happened recently is that I completed a few hat sets. Was there some sort of temporary booster going on I didn't know about, or were the carnival hats downgraded? They currently show as 6. Very frustrating as it has an impact on my arena scores.
Thanks for your help.
