Jan_Driel First, hello and welcome to the players forum! No one from PF here, only fellow players. I guess you know that, when leaving your game open in the background, you need to refresh the page before you continue playing. The problem with the fishing boats is well known and exists at least for 3 years already (that's how long I've been playing) but only on PC, works fine in the App.
Egg Me thinks you might have mis-read our fellow player 😁
