Could be a lot of things, since I don’t know what kind of event you are trying to run inside the spawned actors.
- Check if the array is not empty;
- If it’s multiplayer, open the spawned actor BP class and check “Replicates”;
- Use prints/debug to guarantee you’ve entered the function;
- Try adding a delay node before triggering the event, maybe could be sync problem… Idk, what kind of action/event you want your actors to do?
