Fix Anti-chaos rules

[Connguy]

I like the removal of chaos, but i found one issue. I sent out tripwire 1L to each of my guildmates' 24 cities. Now, even though many of them have arrived, i can only have one attack out at a time, because after that it crosses the 25 line. The "troop commanders" should become available again once a support wave arrives

I agree support should not impede the attcks slots.

When an army sends support in real life doesn't it have a leader/general with it till they return home?
