ok I ran the sim and here are the results:
on turn 3 1st and 2nd BDE (the Cav units) Routed for no apparent reson at hex (41,15) & (39,15) respectivley.
1st BDE rallied and mounted by the end of the turn. There was no reason I could see for the units to rout, although they could see the mass of rebel forces in column on the far shore.
On turn 4 2nd BDE rallied and mounted up. at hex(38,15).
Both units remained combat capable until turn 7 when 1st BDE was eliminated by reb arty. 2nd BDE captured that battery on turn 8, and remained in the battle until the end.
An INF unit eventually captured the lone leader (Pillows) at the OBJ Hex.
I did discover that when using the Capture Artillery rule, you must keep troops with the captured piece or it reverts back to the original owner. It is however uncrewed, and so re-occupying the hex is no trouble.
The battle ended at turn 18 in a reb maj defeat (-625).
So, while I did experience the routing of the CAV units there was no crash on my system and the battle played out well. There was a slight hiccup at turn 15 or 16 when the time turned to dusk and visibility was reduced. Nothing major just a slight flipping of the screen. This could have been because I was watching for the crash and was super alert for any unusual happining.
Hope all of this has helped.
