problem with marius reforms not happening

[Spartan198]

I instigated the civil war and conquered Arretium,Ariminum,and Capua,then did the same,but still nothing.
Then I got to messing around in the Senate scroll,and caused the game to crash. After that,I switched them back to non-playable.

The Senate did actually take Arretium back from me once during a Greek campaign. So they will branch out if they have to.
