what are you playing on?
I'm not sure about deleting/uninstalling updates..never tried it before..however, I would assume if you uninstalled the game, you would lose the update as well, so if you didn't want the updates, you would want to reinstall the game offline..just remember there were 2 updates, and I'm not sure what the very first update did, or how the game performs without it..
Also I'm not sure if you can use a save file created before uninstalling, and reinsatalling the game, you may have to start a new character..IDK..again I have never done any of that..those are just my speculations..
