Too many times I have clicked on it, meaning to create a lake. I can’t be the only one.
I did it a few times as well in the beginning. That’s frustrating when it happens. Another solution is to enable to cancel last use of the wheel (if not used for draw).
I did this a lot aswell in the beginning, and many other players too.
A simple fix would be to add a “+1” text on that button. Then noone will confuse it with lake anymore.
