Does anyone else have an issue with wave in the mat this year?

Our mat won't lie completely flat on the table. The outer edge does, 
all the way around, but the middle has waves running north-south. 
It's as if the middle perhaps 50% of the area has been slightly 
stretched east-west and is slightly too big for its surroundings. I'm 
not sure if the waves are big enough to be affecting the robot's 
travel, but they're certainly prominent.

I'd be curious to know if anyone else has this problem, and to know 
of any workable solutions.
