Seems like 3.6.7 has fixed the crash.

I’ve tested multiple versions of the Unreal plugin, and it looks like this bug was introduced in 3.5.4-hotfix-1 and is there in all newer versions. I had to revert back to 3.5.3-beta to get multiplayer to work. Would really appreciate if someone can look into this. Thanks
