Twin Stick Shooter

I’ve been following this guide:
But I got stuck in Chapter 10 (Twin Stick Shooter - 10 - Weapon Firing Behavior). I followed right after what he did, and in the end I did not even get to see my rifle. He sometimes appears a second in the game and then vanished and sometimes he does not even appear…
My project is: 1013.71 MB
If I need to have virus testing I need to URL to it…
By the way, I’m useing version 4.8.3 of the Unreal engine

Did you manage to figure this out?
