An Issue with Ingestion

Partner Rank: 2

Verification Builds:  1.16.100, 1.16.200

Regression Builds: 1.16.1

Summary: So for the past year and a half I have always been able to submit maps with custom generation settings such as infinite ocean, or anything that the map needs by settings Generation in level.dat from 1 to 2 and customizing my generation by Filling Flatworldlayers with the blocks of my choosing, and it has no problems even in the current version of MC it still works, But now when I submit the project your Sandbox seems to be changing my generation settings back to 1 and making it a flatworld. I was told to make this as a report on jira. There is a thread on atheris talking about this issue as well, the team sideloaded and recieved the same results as me with infinite ocean but when they get it threw the sandbox like they usually do it causes my generation settings to change to flatworld. It was fine on past projects seems like a new issue.

Affects currently Live Content: No

Impact: Unable to submit a map as intended

Repro Steps: Submit a map with Generation set to 2 and setup a custom setting in flatworld layers section on level.dat

Observed Results: (There are a few videos and screenshots within this thread on atheris) 1.  The team reviews the project from Sandbox

2. The team shows that my generation settings did not go threw ingestion

Expected Results: The map should be showing the same generation settings I had set upon submitting it and not change
