I think I’m asking again something very simple but I just don’t get whats wrong whit this
I’m trying to build Consumable actor item like in this tutorial but for some reason when I “click” on Actor its only destroyed on server when it should be seen by everyone. Clients can click on actor but only the server sees it been destroyed. And for some reason clients don’t see Traces at all
Thanks for help!
