It is absolutely baffling that Steam doesn't have a simple prompt saying, "There is a new update available for (insert game title). Would you like to update?" Then there should be an option to automatically revert back to any selected previous version if problems arise -
especially for a game that involves community mods.
For me, it appears that I have solved a few of my new-found problems after the stealth-patch. Apparently, something involving the update shifted around my load order, and after some tweaking I now have everything (relatively) working once again - at least so far. Really wish Steam had a freaking option for whether you want to install an update or not…and I'm pretty sure that disabling auto-update doesn't always work, as I have read in numerous places while looking for a "remove patch" solution that Steam sometimes reverts back to the default option without a prompt.
By the way, still no luck in finding a method for disabling/removing patches and rolling back to a previous version, so to anyone currently playing Skyrim with mods,
do not get the update just yet - I am beginning to fear that once you get an update, you are stuck.
