Molesworth Industry dodgy signage

On the subject of Sat Nav following, has anyone else noticed the Molesworth Industrusty sign on the A14. I went there recently, and as it was an industrial park didn’t go overboard with my route planning… Mistake. Anyway get following the sat Nav and you’re basically going along the A14 and it says turn left, with no slip road BUT there’s a sign on what turned out was a farm access road saying Molesworth industry. It’s an accident waiting to happen for anyone who’s not been there before. When I got to the place they said you should never have come in that way it’s just a farm track, but if there’s a sign that says Moleworth Industry on the entrance to the farm access road off the A14 I can’t see how I was at fault for going down it. Anyone else seen it or done it?

If you want to see photo of said junction go on google earth its Chainbridge Lane Molesworth.
