So I figured out what occurred. Although the event was "announced" live ingame on the website, the servers did not actually activate the event for approx ~45minutes afterwards when the chat and mail servers crashed and some "update" occurred. PW should reimburse those people who opened packs during that 45min period…
Fully support full wipe and servers closed for week+ until ALL CURRENT EXPLOITS are resolved and not opened a minute before. I have legit leveled 5 characters to 60 and geared out 2 of them. Game is in tatters and is effectively trash without a restart.
