You don't happen to get into any pushing matches on your field tile, do you?

(L.A. saw an FRC robot go through the carpet... in the FIRST MATCH... when said robot hit the wall in automode at top speed and kept trying to go to queuing.)

If you have block of something solid, put that next to your field tile, stand on it, and try to push it with your robot. I'll be surprised if you don't see some damage after a couple minutes.
