I've found a little invisible wall just above the water on Pearl. On the peg to the right side of the bridge, just got the left the green plant you start by. Using 13 rod, I go to short range casting. At 100 percent power it should go about 30 yards. However, if you aim at a small section towards the waterfall. You'll see that it can only ever go 15 yards. I'll work out the size and location picture. It acts like a small pier that got removed but the collision box is still there.
