Landscape bug

Hi, here’s a screenshot of the bug

I was sculpting it with the editor’s landscape tools then this bug appeared and I don’t understand what’s happening.

Can you reproduce it every time and if so can you make a short video or list steps to reproduce it? As is, this isn’t really something anyone can help you with.

Steps to reproduce the bug;

  • Create a landscape
  • Sculpt it using the editor’s tools
  • Spend some hours of work
  • Wait for the bug to happen.

I’m precisely here to know how it happened.

I still need help. Can someone give me list of things to check because I really don’t know what to try and I just can’t delete and redo this landspace.

Epic, can I have your assistance please? Like giving me a list of thing to ckeck/try?
