OK so I can fix the issue but only temporarily. If I delete the weapon wheel widget and re-add it, the inputs then work! However, anytime I restart the editor, the issue re-occurs.
If you look closely in the video you can see all the relevant IMCs are set and there actions are being triggered. For whatever reason re-adding the widget must push it to the top of the input handler. If this is the case then something is happening on this widget specifically. The only difference to this and the other widgets is that I’m toggling its visibility, the others I am creating and removing from parent
