Hi I played the game again today right after today's patch update and the bug is still there. I also lost some of my progress after I updated the game, I'm not sure why I only lost some of it I am 100% sure I saved it last time I played the game.
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.
