So, I don't know if this is a bug that should be reported (I'll do it right after this anyway), but in two of my games, I've noticed that water in canyons is kinda glitchy. See attached.
Basically the flow happens on a grid and this is an artifact of that. I want to redo how water flow works so I'm not worrying about this terribly right now.
Please look into keeping canyons with water, they look rather good... Apart from how the water randomly ends now, that is...
