Mesh click and mouseover events not working

Mesh click and mouseover events (create blueprint add mesh bind click etc) are not working IF I do the following:

Load a level in editor
Play In Editor
Go to a different level on play

I was confused when I would sometimes get these events to work but it only works if I load the level in the editor first. Things are probably when not using Play In Editor but that is the mode I develop with so I would like to know why and if there is a solution.
