As of 4.8 Preview 3 and possibly earlier, packaging a blueprint only project with Paper2D and LeapMotionController disabled results in CDO errors for those plugins.

This is related to [Error: CDO Constructor Failed to find long list of engine and paper 2d components - Blueprint - Unreal Engine Forums](https://answers.unrealengine.com/questions/208002/error-cdo-constructor-failed-to-find-long-list-of.html) and [https://answers.unrealengine.com/questions/174942/android-error-cd0-constructor-umgpaper2d-files.html](https://answers.unrealengine.com/questions/174942/android-error-cd0-constructor-umgpaper2d-files.html) but I don’t believe this is Android specific anymore. Neither question seems to address this explicit issue of disabling plugins on Win64, sorry in advance if this is seen as a duplicate.

This is easily reproducible in packaging a brand new Blueprint only project with these plugins disabled on Win64. It seems like these plugins are being compiled into the main engine binary but don’t respect themselves being disabled?

Hello ,

I was able to reproduce this issue on our end. I have written up a report (UE-15977) and I have submitted it to the developers further consideration. I will provide updates with any pertinent information as it becomes available. Thank you for your time and information.

Make it a great day

Open plugins, removed Paper2D and Leap Motion, restart. Enable them again. Restart.
