If no one has answered this by the time I get home I’ll let you know what the problem is as I’ve got one working from that same tutorial. Are you adding it to the viewport when activating it for the second time?
I’ve got a feeling from memory that I ‘remove from parent’ when resuming the game and then add it to viewport again when reactivating the pause menu.
Be home in an hour I’ll grab some screenshots of my blueprint.
