I am having an issue with the river and lake nodes connected to the erosion node. I noticed that when i refresh the graph the shore line and terrain changes every time. I noticed it when i kept opening the file up and realizing the terrain has changed every single time. Its quite annoying. I spent 3 days going through every possible setting, disconnecting and reconnecting nodes and can't figure it out. That is when i found out it happens on the erosion node. Is there a way to prevent this from happening and to guarantee the terrain i saved will always open up as i intended it to without it changing or is this a bug?
