looks like this (primarily?) happens to streaming nanite enabled meshes (in nanite disabled project), not sure if I can localise this further

It sounds like you’re running into a mesh corruption issue in a World Partition-enabled level (UE5). This usually shows up as random meshes disappearing, stretching, showing the wrong LOD, or becoming visually broken when navigating or streaming cells.

Still persist in 5.7 with all possible engine/streaming flags which is really frustrating…. Is there anything I should know about how to work around it or is that a yet uncaught memory corruption? any thought? just give up on open worlds?
