Unable to save edits

I am getting an error when trying to save edits. I am editing a number of point, line, and polygon feature classes in a checkout .gdb from our SDE. The specific error I am receiving is "Unable to save edits. Error stopping an edit session with save edits [Structures]" Just to be clear I am not trying to end my edit session, simply trying to save edits.

Does any one have work around for this, or know what is causing this error?
