There were quests that got completed and didn't count
Peryton quest? You just got confused with the quest text, look at the KillerWhale topic.
disconnects (including during gs)
Sorry, but that's in 99% of the cases a client side problem. In my 3 years of KaL I never had a disconnect caused by KaL, except when the whole server crashed, but then everyone drops. All these ppl complain about having massive amounts of disconnects should fix there settings, change their provider or leave their 3rd world country's, you won't have problems then.
purchases that didn't count, for examples.
I read about that in forums. Dunno, never had problems myself, but I use very standard payment methods (PayPal, instant transaction), I know that some ppl log multiple accs and recharged accidentally on wrong acc, cuz the KaL shop is always based on the last acc you logged in, no matter where you click on the Shop, i accidentally recharged that way on my S1 Charakter myself. I wouldnt be surprised if a lot ppl who do not have received their gold accidentally recharged a friend or alt.
