I didn't realise how against the grain I'm going to be by neglecting Steam Workshop as much as possible - auto-updating mods without your knowledge is horrific, I have no idea why the Workshop still functions the way it does. There's nothing worse than a game updating, and knowing that even though you can role the game itself back to the previous version/have turned off auto-updating to finish your game up, half your mods will be for the new version and half for the old version, because Steam Workshop just updates things without the ability to role back or really deal with it at all.
