Special battle questions

[_Tim_]

I'm playing a generated campaign against AI and have an unusual special battle set-up that I've not seen happen before.

The odd things:

the enemy has changed, every previous special battle was against the same opponent as the battle just finished;

the year has changed;

armoured units destroyed with crew surviving have regenerated with a vehicle. In previous special battles only the crew was available in the special battle - no new vehicle because no access to the repair phase. The only units that haven't regenerated are those with the total loss of both vehicle and crew, as would be expected. But there has been a partial and automatic repair of some units.

Are any of these supposed to happen or is this a bug with the special battle sub-routine?

views please.

cheers,

Tim
