Trainer maker always tests it before giving to Pwizard to post. Trainer monkeys test if game gets reported at least twice to verify reports are valid.
But in this situation some players have the TAB crash bug and some dont ... its possible that the *test monkeys* dont have the crash bug so when it gets tested by the test monkeys and they dont see anything wrong with it the bug might still happen to some players ... ( what im saying is for some players it works like Caliber and for some it doesnt like manzomp , magicMushroom , jambomengaming so we dont know in what category the test monkeys go into )
