I see your anger, but look on the bright side. You would not of had that extra 100 attack to win that next hit in the war. So in some way the Dev's helped you In the war.
I dont think select all eats it up now though. I thought it happened to me, but i have still have my pot ^^ Bad luck though
I emailed the devs, and they returned my lost pot. I'm sure if you do the same, instead of complaining to forums, they will give you another too.
