1 day Premium Bug

I activate my one day premium and it only lasted 8 hours. When I activated it and built some building I thought it was strange the countdown clock in the extra build Que only had 8 hours on it. Sure enough half way through a adventure 8 hour late it deactivated saying my premium buff has run out. PLEASE FIX THIS BUG as I am feeling very ripped off right now.
