"Broken" Battalion continues to fight

[Silver1974]

Game 16, November 1804, battle at I29/17

In Round 7, the Battle Report shows the Neapolitan light artillery battalion failed a morale check. Yet, it apparently continued to participate in combat in Rounds 10 and 11 (there was no cavalry in the battle), and was not counted as Routed at the end of the battle, despite never having shown a round where it regained morale.
