Map check errors are unrelated to `Unreal Revision Control`

What happens when you click the SYNC LATEST / CHECK-IN CHANGES buttons in the bottom right hand side of your editor?

Just throws the cannot sync or check-in due to map generated errors, tells me to check log. Log just says errors, but does not say specifically what.
