While playing on survival, I was building a huge wall to surround my town after installing the latest update 0.6.0. After completion of the wall I paused the game and selected quit to title. About 5 minuets later I loaded my world to find that my wall had been reverted back to its prior incomplete state, while all the resources I used During completion of the wall were gone and my health and inventory were the same as they were after completion of the wall. They were not in the chests that they had originally been in either. Easy enough to say I was extremely furious as all my hard work was gone. Please resolve this issue ASAP. Thank you.
