Crash in Client Marshaller during download of expansion package

[Ryan-Palmer]

Hi Matt, its Ryan from Buzz Interactive. Thanks for the recent update, it has generally been running smoothly but we have noticed a particular crash which happens occasionally in the Client Marshaller. I have pasted a screenshot and here is the trace:

System.ArgumentException: 'jobject' must not be IntPtr.Zero.

@RyanBuzzInteractive, thanks for reporting this. I'll look into it ASAP.

I'm seeing this same crash as well, intermittently on multiple devices.

Error message is:

Unhandled Exception:
System.ArgumentException: 'jobject' must not be IntPtr.Zero. Parameter name: jobject

I thought this might have something to do with starting the downloader from a non-UI thread, but that doesn't seem to have been it.

Hi Matt, was there any progress on this? I'm still getting customers reporting crash-to-desktop whilst trying to download the expansion, some of them getting quite annoyed about it :/

Cheers, Ryan
