4.7.6 crashes on command line Diff

[Zoc]

Hello,

Whenever you run:

UE4Editor.exe --diff "path\file1.uasset" "path\file2.uasset"

Two issues pop up:

First (minor): You need to select a project before you see the diff. Usually this causes the editor to load twice.
Second (crash): The editor crashes when you’re done seeing the files.

I thought it would be good to report on these issues.
I’m using the external diff to compare revisions on Tom Looman’s surival project/tutorial, so I’m using it quite often, and it’s a bit annoying the immense loading time and a crash later on

Thank you for your time and awesome work

Hey Guys,

It appears that this was fixed in 4.8. I’m going to mark this as resolved. If you encounter it again in our eventual release or one of the previews, please let us know!
