Hi Nero.docx,

I’ve tried to reproduce the issue with the following steps:

  1. Launch UE4.5.1
  2. Open Content Examples Project
  3. Open Navmesh level
  4. Select SM_DemoCube
  5. Move SM_DemoCube and play in Editor (No Crash)
  6. Move SM_DemoCube out of scene and play in Editor (No Crash)
  7. Play in Stand-Alone Window (No Crash)
  8. Delete SM_DemoCube and play in Editor (No Crash)
  9. Play in Stand-Alone Window with SM_DemoCube deleted (No Crash)

I was unable to reproduce the issue following the steps listed above. If you can advise any steps I might have missed, I will try and reproduce and report accordingly.

Thanks

Hello, .

Unfortunately, I can’t determine yet the sequence of actions that causes
those errors. This error appeared in version of UE4 that was compiled
in “Development Editor” mode. Also a memory leak [loss] is taking place
for some period before the error window appears.

Since this bug was published, a similar error
was reproduced just once - in “StrategyGame” demo project.

I’ve added error screenshot and some description to my post [reply].

Hi Nero.docx,

In order to investigate this further, can you send me a copy of your DXDiag and a copy of the crash files:

the “UE4.log” Located: Engine\Saved\Logs\
and the “ProjectName.log” Located: ProjectName\Saved\Logs\

Thanks
