Well, it seems that inside a TM some commands do not work, as !!SN and !!AI.

I managed to get a good result with:

!!HE152&v607=2:P54/21/0;
!!AI&v607=2:S152/0/1/81/23/0/5000000/3; **send First wave

!!HE7&v607=3:P55/21/0;
!!AI&v607=3:S7/0/1/81/23/0/5000000/3; **send Tyris

!!HE0&v607=4:P54/21/0;
!!AI&v607=4:S0/0/1/81/23/0/5000000/3; **send Orrin

!!HE2&v607=6:P55/21/0;
!!AI&v607=6:S2/0/1/81/23/0/5000000/3; **send Edric

!!HE3&v607=8:P54/21/0;
!!AI&v607=8:S3/0/1/81/23/0/5000000/3; **send Sylvia

!!HE144&v607=10:P55/21/0;
!!AI&v607=10:S144/0/1/81/23/0/5000000/3; **send Mullich

!!HE146&v607=13:P54/21/0;
!!AI&v607=13:S146/0/1/81/23/0/5000000/3; **send Catherine

I still think that !!AI does not work inside a TM, as they ignore any teleport to get at the specified location. Once I bring them on the other side with !!HE:P then they attack.

I run out of ideas how to give a !!AI outside an event. Now they attack probably because I choosed %200 difficulty. But at %60 I think they will just stay there and not move.

The only working option is to give !#AI in instructions. But then the AI turns are very long, and the game is freezing.

If anyone has an idea how to make AI attack I will be grateful.
