Walkthroughs for custom maps.

Hello! I have a question! I'm stuck on the Paragon map at the point where I need to cross the river using the "walk on water" spell and reach the magical stream, then get to dry land! But I can't do it; the cursor doesn't appear on the stream. I've tried everything, replayed the map, changed heroes, but nothing works. The arrow is there, but the horse doesn't appear at that fountain. What should I do?:smile05:
