I have a question about versioning.
I have two different installation of of Unreal Engine 4.13:
A) first one taken from Epics Launcher.
B) second one git repository of source code.
If I work on a plugin or a project on A version when I try to open my project/plugin in the version B I need to convert the project.
Can you explain me why Unreal 4.13 installed version is different from Unreal 4.13 git repository (branch release) version?
