Followup to this:
I just tried rebuilding UE 4.4.3 from source. If I create a Code Rolling Template project and edit the Ball class, the edits are not included when the editor actually runs. If I add a breakpoint to the class, I simply see the following message: “The breakpoint will not currently be hit. A copy of TestBall.cpp was found in UE4Editor-Test.dll, but the current source code is different from the version built into UE4Editor-Test.dll.”
This essentially prevents me from working in UE4 with code projects.
