Alfred doesn't delete/remove settings by himself, so did you use an app cleaner before updating to the latest build? If so, the app may have moved the old preferences in your Trash, thinking you're installing a whole new app. We don't recommend using app cleaners, as they can be over-zealous and delete essential files like these.
Let us know how you get on. For future reference, it's most likely worth keeping your preferences synced on Dropbox or your Mac backed up to Time Machine (or a similar automatic incremental backup) so that you don't find yourself without your most valuable data

I am having a similar problem. I had my preferences saved in Documents. Today on boot up my snippets and workflows were gone. The backup folder was still there. I tried moving the folder to Dropbox and then changing the folder location. Alfred recognized it and restarted, but it still did not find the snippets and workflows.
