NotSupportedException: The invoked member is not supported in a dynamic module.

Hi,

we started to see this exception in unity editor (all works as expected) after each code change that triggers compilation... Any ideas? It's some internal Unity magic I just cannot figure out what is causing it all of a sudden...
