Unity 5.0.3f2 il2cpp problem: Attempting to call method 'System.Reflection.MonoProperty::GetterAdapt

I updated yesterday to 5.0.3 in the hopes this would fix all my code generation problems with 5.0.1. Thankfully it DID fix most of them, but this one still remains.

I believe the problem is occurring due to XML serialization of a pretty complicated object hierarchy including lists. The call stack is confusing, though, in that it mentions some methods that have NOTHING to do with that call stack. (references to Vuforia and LEMediatorVisualConsole)

I guess I'm going to try to replace...
