[4.10 github] UE4Editor-Cmd.exe - Entry Point Not Found

I’m running from a detached head at the 4.10.2 release tag, and I’m getting a popup when I run the editor:

After clicking OK, it seems to start up okay, but I’m trying to set up automated builds, and the modal dialog is halting the process.
Where should I start looking to get rid of this?

Fixed the problem by deleting everything and doing a hard reset to the 4.10.2 entry. I guess it was some leftover settings from a previous branch/install.
