Detailed description of the issue: When attempting to reload the level using “open level” command with the level name being the current level, the engine crashes completely. Also happens when using the console command “RestartLevel” - with both blueprints and console.
Repro Steps
Action 1: Open level with landscape
Action 2: Delete one component of the landscape
Action 3: Play or Simulate
Frequency: 50% - i have two maps with the same landscape, and it only occurs on one. (100% frequency on one map)
Figured the issue : I had accidentally unchecked “Precompute Visibility” whilst still having a “Precomputed Visibility Volume” in the map. Checking the option and rebuilding everything fixed the issue.
I have attempted to reproduce the steps you provided and have be unsuccessful as far as getting the engine to crash. I have some of my own repro steps for you to try to see if the crash is associated with your specific project or the engine itself. I followed your own steps but also have added my own. Let me know after you have followed the steps and were able to get the crash again.
Create new blank project with starter content.
Select either First Person BP or Third Person BP project.
Click file and choose “New Level.”
Choose the default level option.
Delete “SM_Template_Map_Floor.”
Click on the Landscape tab to create a new landscape.
Keep the default settings and click “Create.”
Select the sculpt tool and add some height changes and bumps on your landscape.
Click on the manage tool in Landscape mode.
Click the drop-down box and select the delete component tool.
Delete either one or multiple components of your landscape.
Click play or simulate.
Observe if engine crashes or not.
Hopefully this can get us on the same page so we can figure out what exactly is causing your engine to crash.
