    Hi,
    After upgrading my HoloLens project from 2018.4.2 to 2018.4.5 I always get about 8 (apparently harmless) errors when I stop play mode in editor:

    Number of tracked cameras doesn't match how many cameras we should have!

    I am using the Emulation Mode Simulate in Editor.
    It's not really a problem but somewhat annoying. It would be nice to get rid of them in a future version - thanks
