There are a number of fairly long-standing issues, that I believe have a serious adverse effect on the game but are not on the Trello Known Issues list. These all need fixing, preferably as part of the next major game update (presumably GU16 to accompany the New World Rising DLC).
My understanding is that you prefer single issue threads, so I will split it into multiple threads. Apologies if I have this wrong and you would have preferred a multi-issue thread.
There is a tracking algorithm problem with trade routes. People quite often see ships queuing for a pier to become vacant while there are other piers available. It seems that the pier for delivery is determined as the ship departs from its origin, not when it arrives at its destination. This didn’t used to be a problem, but it seems that something happened around GU12 to make it worse.
