Lost my data

beat every boss on every difficulty had every weapon full cortical and every character as well as a lvl 15 warpig, many other lvl 10 characters. lost all of that, is there any way to get it back.

Same problem. I had Nova 13 lvl, full equip set, game was lagging so i reset computer, after loading windows and entering game there was no data. I have replays to proove that.

It happened to a friend of mine too, luckily he had played just one time so he didn't lose much. It seems like that if you get out of the game in any way other than leaving from the menu (pc shutting down, game kicking you out for lag, stuff like this), you will lose your saved data. There should be a way of making a manual backup of the data, provided you find the correct folder where Ultimate Boss Battles' saves are, but i don't think there's actually a way to get saves back once you lost them..
