I am doing the Watchtower quest. I have been following the Wiki guide https://oldschool.runescape.wiki/w/Watchtower. When I come to the broken bridge right before the guards who give you the Skavid map, it gives me the response "I can't reach that" when I choose option "Jump-Over" by clicking on side of the gap for a red X option. I retraced my steps and even spoke with the WIzard in the tower. But can't progress beyond getting the Skavid Map, Please help?
