I have a problem that seems to occur at random. Sometimes when I click on a ship or fleet, the ship(s) I selected previously do not become deselected. (The ships are on different tiles.)
This means when I give orders to my ships, I'm accidentally giving orders to other ships, which then change course and decide to head off into the unknown.
It doesn't happen constantly, so I don't know how to predict what is causing it.. The only workaround I've found is to click on a planet/star after giving orders, before clicking on the next ship.
Does anyone know what causes this?
