I've done a run through the whole island trying to get all of the "Under the Bridge" collectibles, and I'm still missing 3 according to the game.
I've been using the extremely helpful map that was put together by the guys over at Achievement Hunter. Two of the bridges were never counted. For reference, on the AH map, the two that won't register are #49 & #50 (just under the horse racing track). I've tried loading a save, restarting the PS3, etc. but nothing works.
Anyone else have this issue? Any suggestions?
That still leaves 1 bridge that I'm assuming didn't pop for me either because 49 & 50 are the only ones left on the AH map. If anyone's had any problems with other bridges let me know so I can narrow down my search.
