Hydro Flask Wide Mouth Bottle 32 oz

I just purchased this as a replacement for the same flask that I've had for two years. For almost all of that time, it worked well, each night being filled with cold water and sometimes ice that stayed that way through the night. I always cleaned it by hand in the sink, until recently, I put it in the dishwasher with a heated drying cycle. After, it wouldn't sit level on a surface; it wobbles. More importantly, the water no longer stays cold through the night, and the ice melts, so it essentially broke in the dishwasher with a heated drying cycle. So I won't make the same mistake again. It just vexes me that it is advertised as dishwasher safe, without any reference to a heated drying cycle, which, of course, all dishwashers have.
