Support thread - shooter bp project

Everything is set like that, I never changed anything in this actor, mostly just the gun parent. any idea if something done in the gun parent would cause this error? Where is handling part set? I think I might be able to backtrack to the problem. It is also worth noting that the markers do not appear on the gun when you click the part you are trying to put on the gun. I did copy paste the sockets to add more areas to put stuff on the gun but I figured that wouldn’t harm anything being it worked fine on the server. Thanks.
