[j-mie]

Torch Version: v1.3.0.59-134-g93fa822 SE Version: 1.187.89

Expected Behavior

Observed Behavior

What actually happened? The exception was not handled and the server crashed without restarting

Other Information

Stack Trace:

My theory is that the game is running in another AppDomain? Hence AppDomain.CurrentDomain.UnhandledException += HandleException; not working?

[Jimmacle]

The game is definitely all in one AppDomain. It's likely something to do with Havok being native code so exceptions may not be handled the same way.
