In the test LT47 game, many tiles around cities have sunk due to global warming; and pollution on islands was not cleaned because my auto-settling engineers could not get there. In a real game, I probably would not be able to use auto-settlers due to war risks, but however: could we make auto-settling transports be ready to serve the needs of transportable auto-settling units?
The same could be asked about road-to and autoexploring advisors, though in the former case the transporter should be assigned to another duty than the rider (maybe make a "taxi service" advisor?).
