For the second part, the problem is solved by adding a “forceReplicateNow” node.
I added a breakpoint on the EventbeginPlay node and it seam that it fire two times, one when using the primalitem and one when placed on ground, i think there is two instances of the object created, and it seam that on dedicated server, the first don’t fire the beginPlay event. How can i access to this “before placement” thing and change his size? Or at last how can i see if the event fire ingame, is there something like “printString” but for in-game environment, can i send a chat message?
