Heat will warp your board. You should not iron on, leave in hot car, or in sun. I think I warped my 1st board along time ago and then kept it under some very heave objects to press it flat for a while. It is still usable.

Heat is the culprit and, probably, the fix. I found out that my desk lamp, one of those on a long adjustable arm, will warp my mat if I leave it on overnight!! In that case, turned off the lamp (duh!) and put a heavy pile of books on the mat. Fortunately, the mat unwarped after a couple of days. Good luck.
