Stuck packaging project in UE 4.12.3

Hello jasko81,

Unfortunately since I’m not able to reproduce this on similar hardware, I’ll be resolving this issue. As mentioned we do have a working workaround which is usually good practice when you have content in your project that you’re not using, as it avoids packaging unnecessary content. If you get blocked by this issue again, please let me know and I’ll make more attempts to reproduce the problem.
