[CrashReport] UE4Editor_Engine!FNetGUIDCache::GetObjectFromNetGUID() [packagemapclient.cpp:1876]

• I loaded up a two player game in the 'play in editor'. Upon clicking into the client, the game crashed. Clicking into the server did not cause it to crash.
• I'm pretty sure this happened because I checked out a file and then reverted it using the editor. Then once I tried to run a match it crashed.
• Changed some card data assets by giving them a different icon texture. Saved and ran a match. Exited and reverted them using the editor and then tried to run a match.
• Installing something else, unrelated to the engine likely a forceclose.
• Tried to start a game in two-players.
