@jchristof Does it only happen in the emulator?

@jchristof, is the code snippet you provided something you added to a script?
Thanks!

found it. thanks! i'll was not seeing an exception on my flighted HoloLens. I will continue to investigate on one with the version you mentioned.

[jchristof]

Thanks guys!

[david-c-kline]

I have not been able to repro this using the emulator. I recall fixing this issue for the 2017.2.1.4 release...

@jchristof, if you re-download the 2017.2.1.4 package, or try the may18_dev branch and can still reproduce the issue, please reopen it.

Thanks!
David

I stand corrected.... I just saw the exception.

[david-c-kline]

my exception is occurring in OnSourceLost, but may be related to this.

NullReferenceException: Object reference not set to an instance of an object.
