I would go back to basics with the house breaking. When we moved I had to do that for about 3 weeks. It sounds like they think it is ok to go where they want so you have to retrain them. They would not do it to act out they don't really think that way I hope
I would get an expen or keep them gated in the kitchen and make sure they do their business bf they get let out.
If they are trained to go outside then I would walk them for 15 min bf bringing them in. If they are pee pad trained I would make sure they use them bf I gave them free run of the house.
Basically I would start over and be very consistent with where I wanted them to go. It can be very frustrating....but remember we are the ones doing the training so if it isn't working we are doing something wrong..
