The prison is full event 捕虜がいっぱいです;  occurs with a much lower priority than the Shimazu stealing a commander event 島津／引き抜き;. The only thing is that the Shimazu stealing a commander event only occurs if the random commander selected from your army is female, not at love and not suzume (important). So there's a 1/however many commanders you have chance of it triggering.

Definitely agree with your assessment that that some commander is probably on 配備, triggering that return 1 under iic2 == 0. Why did they code it like that?!

I can confirm that the enemy turn cover screen uses the キャラ数 function to populate the number of commanders - this can be seen in tagSeiryoku::create - so that 59 does not include the 配備.

On the bright side, that's means we can simply fix this bug by putting 空き番号 as the condition in the clause above instead of キャラ数...

My understanding is that all 4 of the brothers go on 配備 after 島津／天下を目指す. So that's probably what is causing it?
