Walls rengerate

[Danny Martz]

I have X4 and just experienced something new when editing some 1st floor walls of a plan. If I pull an exterior wall back from an intersection point, whether it be a corner or a wall break, the wall regenerates. It is happening only in the x4 plans. If I turn off auto rebuilt attic walls it doesn't do it. But I can leave it on with plans I've created in older versions and don't get the auto wall generation. It doesn't seem to do it if I delete roof planes either. Not sure what's up. See attached. Thanks, Dan
