so I did my first all grain which went off perfectly. Hit my mash temps perfect. Preheated my tun with hot water for a few hours, doughed in at 170*F and hit 154*F. Sparge with 175*F water. Hit my volumes and gravity on the dot, but as I cleaned out my mash tun I noticed that the walls of the cooler kinda warped or bubbled a bit. Anybody had this issue? It's an Igloo 50 quart Island Breeze Maxcold.
