I'm trying to beat this battle square think, but my party stays in attackin behavior after beating a couple of monsters so ı can't save may position..
they didnt return to normal after finishing the first rank..

That's pretty odd. You can't rest while in the process of beating a rank, but after the golem declares your victory, you should be all set. Your Party isn't spread out too much is it? If there are active spells in the area you won't be able to rest either (skull trap, stinking cloud, etc). Have you walked up and down the hallways to make sure that no wandering priests have wandered into your area of influence?
Why don't you try going up the stairs to the first level and resting there if you are still having problems.
