Hello!
This was tested on Unity 5.4.0b18, though I think it may apply to 5.3 as well. Let me know if I should post in the beta forums instead.
We are receiving an access violation pretty consistently on our game map. I don’t know what triggers it, but we can usually get it to trigger within 5 minutes just scrolling on our map.
I’ll be uploading the project and including the crash dumps. I’ll reply with the bug ticket # once I receive it. I wish I could be more helpful but I’m not sure what data you need.
