Sigh
I had the same issue with all my projects.
I don’t know why but UE system believes that I have some custom version of the same version and requires full recompile of the projects.
I thought that if it would be plugin there would be no such issue.
The project is compiled under 4.11.2
&stc=1
Just recompile it. You would need C++ source of engine.
I am really sorry. If anyone can help with this issue I would be really grateful.
With Best Regards
