Hello, glad you’re enjoying things thus far and I’m sorry about the bug. That was actually something that got altered in 0.15.3 I believe. Are you on either that version of 0.16 of the game? I’ve yet to see it bug out since those patches but it’s always possible I suppose. Your game version is listed on the title screen in the top left corner.
What version were you on? Until the hotfix I put out today (0.16.3) the water in the swamp wasn’t really considered water. I’m sure that sounds dumb but basically unless you are on 0.16.3 you’ll have that issue with water in the swamp. If you are on 0.16.3 and this is still happening however please let me know.
