Construction trailer missing - Not a Drill mission

The construction trailer is missing from where it should be. There is only the rear wheels of the trailer showing and nothing to hook up to. have tried restarting the game numerous times. This is in a Co-Op game. I have attached screenshots showing where it should be and what it looks like when you get to the location. I tried to upload the screenshot but it won't allow it

Your screenshot need to be below 1Mega octet otherwise it doesn't want to upload, use paint to save them in .jpeg for exemple and eventualy resize them too.

I bet the pikeys took it! Can't leave valuable stuff like that laying about with no security!
