Yes, this can be a problem, especially in tanks that have larger inverts that move around the tank.
The best thing to do is setup your foundation very well then tie or glue your rocks as you create the rock work. Don't ever lay rocks up against the aquarium glass.

I find that my snails move the rocks around, and knock my corals off their perch. Cowrie snails are especially bad. I have found that building rock is very different than building houses out of playing cards......the rocks need to be stable and able to withstand some shifting and movement. Good luck!
