I just had a battle with reinforcements without a CTD.

1. Romani and general besieging Patavium vs Independents at Patavium without general
2. Independents had reinforcements, but during the battle a message came up which stated that they would not arrive in time to participate; however, at the battle's conclusion the reinforcements were included in the unit count and actually managed to inflict a small amount of casualties upon me.
3. v0.74
4. NA
5. NA
