More 12.5 bugs! - wall style change

[msclark]

I changed the center cavity of an existing wall style from 5.5" to 6" and when I replace the wall it extends to infinity both directions, then if I try to move it it seperates into pieces, ie -cavity, outer sheathing etc! If I try to re-join the wall to correct the infinite extension, Vectorworks locks up and has to be restarted! What I really want to say here is why the hell is every release so buggy, do they actually test them? But I should have learned my lesson by now and not upgraded until the maintenance release. Has anyone else experienced this?!
