Cast To Problem - Warning: Looks like a wire-trace was not injected before the jump

I’ve seen a lot of questions about this and tried various solutions such as deleting the wires, redoing the whole blueprint and reopening UE but alas I’m still greeted with the following warning:

Warning: Looks like a wire-trace was not injected before the jump from ‘Cast To AI_Racer’ to ‘Cast To RacingLine’.

Any other ideas to fix this?

As no one seems to know another solution to this problem apart from deleting the wire or redoing the blueprint I’m just going to mark this as answered.
