Hey Cobrysis,
Thanks for pointing that out. That has been fixed in our internal build and will likely be fixed in 4.6 as part of new Blueprint menuing system. It appears it was one of issues that was not fixed in time for 4.5 Release’s New Blueprint Menuing System experimental option.
I will check with developers and see if there’s any way to hotfix that. In meantime, you’ll need to disable that experimental feature when you need to search for a cast to node, and then enable it again when you’re done.
