Scipio Africanus took Mediolanium by storm, then moved on to Turin. Meanwhile, the siege icon of his army, complete with himself and the army, remained at Mediolanum. Africanus #1 continued to take Turin and Potavium and finished his turn there. He was replaced by another leader next turn. Meanwhile, his double remained at field. He did not try to move anywhere for the reminder of the game, at peace with being a ghost. Of sorts. He did try to intercept smaller armies. He was kicked out to Etruria when another Roman army refused battle in Cis. Gaul.
Meanwhile, I did hunt down Africanus #1 (or Africanus #3?) in Bruttium and killed him. His ghost hardly noticed
Other bugs... troops count in the ledger appears to be wrong at times. By turn 20 Romans clearly had more than 12 militia units. Infantry count was just off 1, which I could have written off, but 12 militia in the ledger vs some 32 on the board, that's a bit too much.
