Metal Bird Danger sign not working

[MiloHoney]

im trying to do the forzathon weekly challenge for the 1932 Ford De Luxe Coupe. I keep getting 1750 on the Aerodromo en La Selva Metal Bird Danger sign (3 stars) but for some reason it isn't completing the challenge for me. Yes I did the 3 previous parts of the challenge, and only this one isn't working.

The Danger Sign at the end of the Runway is the wrong one....the one you want is about halfway down the runway off to the side (left hand side if you are heading towards the one at the end). I realised that the other day after about 5 attempts. Metal Bird is one of the temporary "Evolving World" PR Stunts. The 3 Star distance is about 600 feet or something

It's a blue (temporary) danger sign, South of runway, using wreck of a plane as a ramp
