It's time to learn what this Nexus business is all about.
I HIGHLY recommend playing in another browser other than Chrome for the time being. I thought Chrome was deleting data, but it's not...you just can't see it when in Chrome. Your data should be perfectly intact once Google fixes their browser.. I wish I knew why, but this is out of my hands.
Anyway, good luck dying. This update is not for the weaker among you. Seriously, good luck! And thanks for being patient.

Oh and you guys who are dying, just do your reading. Game hints are golden. I've not died since I've started using DODGE against abominations and depleting riot guard's tac-bars by meelees. Also you can shoot sleepwalkers to body to make them explode other enemies or to head to kill them fast. Also going back for left guns rewards.
