I've got a query.

In a game I set up three masters (two S3E1, one S1W1E1F1) and at least four slaves (S1-2; E0-1; W0-1). I set the S3 masters to earthpower, then blade wind, the other master to cast acid rain. They were placed about mid-way in the set-up area. Instead of doing what I ordered, they cast other buffs and then stuff like mind burn.

I thought I might have been out of range as my enemy was set up at the back of the battlefield, so I put my mages very close to the front. Then, same situation second battle, they just cast buffs and troop buffs.

Is a 25-30 range spell still unable to reach the back of the battlefield from the front of my setup area, or is there another problem?
