Build type: Source

Build version: 4.10.4-0+++depot+UE4-Releases+4.10

I’m experiencing random crashes, usually when opening a map with a quite large landscape. I wasn’t able to find any special conditions for the crash, it happens very randomly: sometimes it’s not occurring in 30 minutes of gameplay and sometimes it could happen twice a minute (granting very similar game sessions).

Here is an output from the VS log during the session, which lead to the crash:

Callstack state at the moment of the crash:

849×510 16.3 KB

The cause of the crash seems to be the assertion here:

I can see that you’ve changed the class a lot in the last releases and this issue could already be solved, but unfortunately I’m enable to update the sources, as the project I’m working on is about to be released.

If possible, could you please give me a hint on how to hot-fix this bug or what could be causing it?

hey Elringus-

According to the VS log provided, it seems that there are a few assets referencing the WhiteCapsule material but are unable to find it. If this material has been deleted, please try fixing the redirectors for the project. You can do this by right clicking on the Content folder in the Content Browser and selecting the option for “Fix up redirectors in Folder.” If you are still having this crash occur after, please provide the project logs (in the Saved/Logs folder of the project directory) and the callstack / machine ID from the crash reporter window.

Hi ,

Fixing the material ref actually solved the problem.
Thank you very much for the help!
