It was recently brought to my attention no one has ever seen the "campground" structure (camp_1.nbt, camp_2.nbt, or camp_3.nbt) in Minecraft Bedrock Ancient Cities. I did some analysis and indeed, no Ancient City appears to contain them. Further research showed the Minecraft Windows executable never even accesses the .nbt files for the campground structures on Bedrock.
Steps to Reproduce:
Go to any Ancient City and look for the structure shown in the attached "campground.jpg" image. (Obtained from Java Edition.) Here is an example seed with all the nearby Ancient Cities checked:
However, since a negative cannot be easily proven, file access was checked to see if any of the camp structures were being loaded. I used Process Monitor and set up an inclusive filter for camp_, sauna_1, and ice_box_1.
No camp structures are present at any of the Ancient Cities listed above, nor were any of the camp .nbt files loaded. The control cases sauna_1.nbt and ice_box_1.nbt were loaded as expected to verify the validity of the test. (See attached "mcio.png".)
Bedrock Ancient Cities should generate and load campground structures as Minecraft Java Edition does.
