Thanks for your quick reply!
Well as i mentioned the ad-bug works for every booster. I have like 800 Fitness-boosters (green) because my buildings are all maxed out and i receive a good amount if green pack from there. I think this new 4 X training before each game is a huge deal breaker... i hope my green packs will last me long enough
You don't have to watch the videos just press play and do something else while it playing in the background ;D
