All base structures disappeared after steam update
Steam appeared to do a quick update, and I logged into my previously fine local seed. I can see that my spawn is still set to where my bed was, but nothing is in the world in terms of structures I made. I made these structures over 2 - 3 days.
Happy to provide logs if someone lets me know how? All my items are still equipped and untouched. I took a screenshot of me standing on my "bed" / spawn point and attached.
