Dear DForsey,
Hi there! Welcome to the UE4 Forums! I am happy to have witness your first 2 posts!
I have now fixed crash (update to follow), thanks for letting me know, I’ve also deprecated the plugin version of LoadLevelInstance because is one of my BP nodes that is now in the main engine. If you have questions about the node in the main UE4 engine (it’s been live since 4.13) let me know 
Also everyone remember I like hearing GOOD news too.
