when i try to teleporting, i dont end up where my marker is but i end up in a lake. always the same lake.
You might just be trying to get to a place that isn't open to you at that point in the story line.
had a friend who thought he found a hidden super chest in a lake and when he swam to close the game reset him back to the surface facing away.
In reality the section the chest was in was unlocked later on and he was able to get it.
