This ramp is incorrectly named as “M4 (E) J33 Exit to A4232”. That should be “M4 (W) J33 Exit to A4232”.
There’s a “General Error” UR there as well. Without any further details given and nothing apparent in the Waze & User routes, I have no other clue as to what the problem might be. There were a couple of revcons on the roundabout, which I fixed, but I don’t think those will cause exit-counting problems.
Please fix the ramp name and close the UR - solved or unidentified as you see fit.
