    I have an intermittent bug that is driving me nuts. Our app loads in asset bundles when users select a character. I flick back and forth resulting in loading, then unloading a character over and over again eventually , but unpredictably it will crash.

    The crash occurs on a Nexus 9, but not on a HTC m8. I've been trying to track it down using various methods and have finally given up.

    I understand that the error is a null reference and it seems to always be in DrawBuffers. In terms of timing it always crashes after the bundle has been loaded and instantiated and appears to be on the first frame it would be rendered.

    Anyone experienced anything like this ? Anyone got any ideas ?

    I've tried eliminating nearly all the other code from the app one part at a time until it was pretty much just loading and unloading the bundle. Cleared up some memory issues. I've changed the render settings , got rid of static and dynamic batching, turned off shadows. Tried different character bundles. So far nothing.

    Desperation is setting in.

    Here is the debug output:
