The weird thing is that until recently I never had any problems with sandwiching - I just did it and it was fine, but recent ones have all gone wrong.
Just in case, you might want to have a bit of a look at the pad under your carpet (may have worn out and have no give in it) and your subflooring (may have worn out and gotten squishy). The fact that you hadn't had any problems before suggests the possibility that something about your floor has changed and, sadly, that is rarely good news.
