I was over on Kongregate platform tearing through my fightlist trying to level up fast when i realized something. I accidentally raised the fight boost to use 4 stamina instead of 1 with all the jumping around. There should be a little checkbox to lock/unlock the ability to use a fight boost.
I gave this a ten. I have had the same thing happen. Even if they moved the boost to under the fight list or somewhere. I think with the page jump and placement, a few people are having this problem.
