Trying to Set Array in Game mode But accessing None o.O

Below are some screenshots, I am trying to update a warrior list array in the game mode to tell each player controller to update their respected warrior list thru the game mode.

The list is a collection of widgets on the main menu widget. Children to a scroll box (not sure all this info is relevant)

Below is the error log

I have tried using a normal add instead of add unique and get the same result


Now I have noticed that I only get this error when more than 1 player is connected. So if i run only one player i do not get the error at all in the client net mode.

I’m assuming the cast is failing?

what would cause the casting to fail? how can I fix it?

The main problem would be that you are not using your game mode.

Have you set it in the world settings, game mode override?

Yes it is set for the level
