Bug: AI doesn't buy/deploy mines and obstacles

[dTerm]

Sorry for digging this up again.

I spend the afternoon running about 50 random assault games via the battle generator, all had different opponents and were set at 'June 2024' with player 2 being the defender. In only 4 games the defender had deployed mines, never ever wires/DTs. From the 10 games I let player 1 defend, all had mines/wire/DTs being deployed. I restarted my computer three times in between.

Afterwards I did a couple more games, and set 'human deploy' to check whether build points had been bought. Player 1 had always spend 80 points, player 2 always zero. Map size was 50x100.

So this brings up two questions for me.

In the manual it is stressed to let player 2 be played by AI, when designing scenarios via the editor. Is this because of underlying programm behaviour, or merely as convention?

Does this 'rule' also apply to random games via the battle generator? My understanding has always been, that I can freely choose here, which side would be played by me, and the other by the computer.
