Heres a warning for anyone on the web version, I'm pretty sure whenever theres an update, your progress is essentially deleted. Thats the only conclusion I can come up with for why my progress is gone.
Thanks for the heads up! Just over level 20 and just unlocked Epic rarity with a build that is starting to weather the areas smoothly. I'll keep this in mind if I ever have to restart, but at last if I do I can treat it as a league system like what I'm used to in PoE, and next time I'll already have a serious edge when starting off.
