So I’m experiencing a crash with nativized Blueprints which I have not experienced before. I’m in 4.18.2.  
First I thought it was this issue: [Unreal Engine Issues and Bug Tracker (UE-43458)](https://issues.unrealengine.com/issue/UE-43458). But that error happened during packaging and not when opening a packaged game. The solution to that issue was not having 2 function libraries referencing each other. I only have 1 BP function library in my project so that isn’t the issue. I do however have some Macro libraries, I’m experimenting with what happens when I don’t use those.

Most likely Event Driven Loader will rid the crash but I’d still like to report this regardless and find a solution.
