Wire trace not injected before jump?

I’m seeing my log completely spammed with the following error from a Blueprint construction script:
LogConnectionDrawingPolicy:Warning: Looks like a wire-trace was not injected before the jump from ‘Cast to Path’ to ‘Set Path’

The fact that it t is being constantly spammed is killing the frame rate in the editor.

Is it possible to rebuild the BP from scratch? Ive never seen this error before.

Sure, if I want to waste a weeks worth of work.

Yeah fair enough. Try disabling parts of the CS Logic and see if you can get it to a stable point, after that re enable what you disabled until the error comes back, you may be able to narrow down the problem nodes that way.
