3D UMG widget not working on more than 1 viewport or client.

Hey guys,

I’ve been working with 3D UMG Widgets using the Widget Interaction component which worked fine up until I tried testing with more than 1 viewport (hitting play with Number of Players > 1).

With more than 1 player, no hover events are registered and clicking results in no OnClick events being registered (note that the button’s Click layout effect does get triggered).

These are the relevant blueprints:

I’m not sure what’s wrong, especially seeing it works just fine on 1 client; is this an engine bug?
