I recommend NOT to update. I carefully chose "NO" so it uninstalled my mods and I carefully reinstalled them all using NMM newest version + Wrye Bash + LOOT and everything needed. The game is totally messed up and new install couldn't save my saves, which are now bloated and useless. When would I recommend to update? First of all: Never, if you really have to wait till you are bored with your current playthrough, then delete ALL game files, ALL folder and then reinstall. It might work. Might. 0.56.1 works great, no bugs, I see no reason to update.
