I'm pretty sure that the problem is that the multiplier is based on achievements. As the game progresses, it gets harder to get achievements/multiplier at the same time that it gets harder to progress with the girls, which leads to nothing ever happening
There seems to be a glitch on the reward system days where you receive a random item. I don't know if anyone else is experiencing this, but I am getting an item as well as a chest in my consumables page. When I attempt to open the chest, the game crashes.
@Raja and Colin: If there was to be a pvp arena, it would give melee classes a disadvantage. And only those with either terrible or maxed equips would go in there.
wow, lag is really a double edged blade. It's saved me multiple times, but can keep me out of getting good stuff. Oh well, guess we have to deal with it.
