Ships on certain trade routes may spend an excessive amount of time at a dock doing nothing. For example, a cargo ship may in the worst case be docked for 5 minutes at a port unloading and loading exactly zero goods.

This happens when a trade route unloads and loads the same type of goods at a stop. For a cargo ship, the worst case happens when unloading and loading all slots of the same type of goods. For example, unload 300 wood, then load 300 wood, which takes 5 minutes. The calculation sums the unload time and load time separately, even if nothing is unloaded or loaded, which does not make sense.

Trade routes such as these are often used by players in combination with minimum stock limit when production/consumption rate of a good is often changing(due to trade, docklands, etc.), so it would be very disappointing if this bug is ignored simply because such trade routes are used more rarely than regular ones.

I installed the Game new on 05.09.21. Now all Achievements from the DLCs are unlocked - BUG. I never played one of the DLCs.
I own Season 1,2,3. It would be nice to reset the achievements.

I recently purchased Anno 1800, and have installed all updates as of 28 Sept 2021. Then I began a new game today, where Beryl O'Mara offers an early optional mission named 'Clueless Courier'.

This delivery mission sends me to a lighthouse near Mullbane to pick-up 10 tons of 'None-Of-Your-Business'. After clicking several times on the lighthouse, I was eventually able to pick the cargo. Unfortunately, once I have the cargo on my flagship, the mission does not show where it is to be delivered. Since Beryl O'Mara has a ship sitting in front of my harbor, I suspected this was the delivery point. Sadly, clicking once beside the ship does nothing. As of 28 Sept 2021, this mission appears bugged.
