Was gearing up to attack the alligator boss, ran from house in jungle to house in the desert to drop off extra supplies. When I arrived at the location, the house, Derketo later, campfires, and all supplies were gone.
Logged out for the night.
Next day, logged in and went to boss alligator, after killing him, went to 2nd house (jungle house). Everything was gone except this time, there were bags of items (crafting supplies and food) along the shore and in the water. House, alter, camp site, was all gone.
However, an extra outside sleeping gazebo was still intact.
