Sept 18 Patch and Exciting Base Game Update

I am in a quandry.  The last time I patched was the update prior to 7/23.  I have heard quite a few people not being able to even open the game, it freezes after a few minutes, it crashes even if it starts up, and the save error, which I saw was supposedly fixed in the latest patch.  My game due to many issues I won't go into is very important to me and if I patch and can't play, I don't know what I would do.  It may not be something that I could fix on my own, and if it is on EA's end, it would not be something I could count on being fixed for a while as they are only doing fixes every other month.  I really want to participate in the grim reaper event, buy the story book nursery kit, and just play with direct x 11.  I am so scared if I patch and update my mods the game won't work.  So should I update or is it not worth the risk and possibly like others break my game?  Any input would be appreciated.
