Not sure I'm in the right branch - it's the Steam version of the game.
In any case, built a large reservoir for water and filled it. Built a pump underwater, turned it on. It worked. Then, it didn't. Next time I look at it, it claims the pump isn't submerged although it obviously is. Photo, output log, and two save games attached. One save is some time before the issue, the other is after.
Thank you! Awesome game!
Unclear. Put a pump underwater, turned it on. Usually works.
