Unexplained Terrain Regions Streaming Out

Bug Reports Engine Bugs

#1

Approximately ~1hr ago our users started reporting client-sided loss of Terrain regions. We have not updated nor changed our game in any way to be affected by any new code. The issues imaged below are from our users’ reports and the bug reports coincide with a Terrain related FFlag being flipped: VoxelGridNew4 (this is our assumption).

Because the Terrain regions dropped are client-sided, players are effectively able to no-clip through the world from this newly introduced behavior.

Hi, thanks for the report. We disabled a new terrain feature for your place. Let me know if any issues remain.

Some follow up questions.

Are you using streaming? If so could you share your configuration (listed under Workspace → Streaming).

For the player reports could you describe any additional data from the reports, like platform, Client version, etc.?

#3

Yes we are using streaming.

All reports have been made by users on laptops/desktops.

Yo, did you re enable it for my place? Booga booga reborn 11729688377, it’s happening again
Could you disable it again for my place as well?

I’d like to point out that I’ve also only gotten reports from desktop users
