Got this crash while removing some static meshes on sublevels. Might have clicked on foliage or landscape accidentally too (there was some stutter since had much sublevels visible). Attached dumps.

Hey SaOk,
Could you provide me with some more context so I can reproduce the crash Screenshots and some simple steps should suffice. Screenshots of your ‘Levels’ tab and how you are using level streaming is also going to help me reproduce this crash.
I used your MachineId to look up the crashes you have experienced within the past two weeks, and could not find the crash you are reporting here. Did you make sure to submit the report after you received the crash, and are you able to consistently reproduce this in your project, or is it a one time crash?
Thank you,
I use the world composition, levels are assigned all to same layer with same streaming distance. I have got similar crashes before too, but only once checked the error message to be this. I believe it happens when having much levels loaded to cause cause low frame rate. Then just clicking fast between placed meshes, landspace and foliage. Maybe even the sublevels arent related to this crash. Just need to have heavy map loaded in editor (~40k placed meshes, few millions foliage, grass layers…).
I sent the crash report normally, but might have left the message screen blank if it affects. My crash reports have reached destination very randomly before too.
This seems like it could be related, or the same as a known and reported issue.
Could you provide me with the full callstack generated from the crash so I can compare it with the reported issue’s callstack?
Thank you,
