Procedural Mesh Component Blocks Level from Saving

When a blueprint is added to a level that contains a procedural mesh component the level is unable to save. The error message that pops up is attached as a screenshot.

Edit PatrickD (08-29-2016):
Compiling and saving the blueprint works as expected. Compile and save the blueprint, then put an instance of it in the level, then save the level, and the level specifically fails to save.
