OK noob question here but if the payout is not occurring because I inputted the wrong wallet address, it would still read as payed out on the account screen, right? Am I understanding this correctly?

So I'm fairly new to mining. I've successfully mined ETH. Thought I'd give PIRL a try just for fun. Is this payment problem something that happens often in mining pools? There are ~1800 miners so and growing so these miners must be getting paid no? Should I be worried?

has anyone had problems with payment on pirl.minerpool.net?
