Hello, unfortunately the model name or the namespace were not changed (and i don't think i could have changed them by mistake... the changes made before that last deploy, had nothing to do with that entity kind). More, i cannot explain those 2 weird things: the test app (the one deployed) behave exactly as the one default (it was sending chat messages for testing from the default application's ID, the queries on the changed tables responded as if i was querying the default app) and most important, the CPU time grew very very fast, about 20h in about real 2-3 hours. The missing data totaled about 1500 entities 2Kb each so even if there wore deleted programatically it couldn't have consumed that much CPU right? I am also concerned that nobody from the app engine team responded :(. Even a "this is what you've done bad..." response can help.
