Currently it cost the CSA player $50,000, 25VP and 2NM points to move the capital from Montgomery to Richmond. That isn't much incentive for the CSA player to move the capital. There were several reasons the capital was moved.
..."on April 22, [CSA Vice-president] Stephens met with [Virginia] Governor Letcher and the next day Stephens met, behind closed doors, with the state's secession convention. Stephens strongly encouraged the Virginia secession convention to adopt a treaty with the new Confederacy, adopted the Confederacy's provisional constitution and apply for statehood in the Confederacy. Stephens suggested the possibility that "if such an alliance is made . . . the seat of our government will, within a few weeks, be moved to this place." Stephens reiterated the remarks on April 23. His rationale, with which he hoped the Virginians agreed, was that the Yankee army would soon be knocking on Richmond doors and Virginians would be better off to have Confederate Army troops to help the Virginia militia greet the mudsill horde....
By the thinnest of margins the Confederate capital was moved from Alabama to Virginia on May 20th 1861."

Has there been any thought to an event moving the capital or a penalty for not moving the capital?
