Summary
When choosing whether to auto-expand rail, the AI gets confused about market access from convoys
Description
The auto-expand button when used on rail will expand if the railways are 100% staffed, are either subsidized or have 80% gold reserves, and the state either has expensive transportation or less than 100% market access. This causes the auto-expand to go berserk building unnecessary rail if market access is impaired for a reason that more rail wouldn't fix, such as your convoys being raided. If you're playing a subject of GBR for example the auto-expander will build absurd stacks of rail whenever your overlord gets into a long war.
Steps to reproduce
Have rail set to auto-expand and get your convoys raided or isolate your market capital
