Hello,
Sorry for the confusion here, this event seems to end at 23:59 server time on 25th, from what I can tell. The forum's listing is in error as it is just a preview; the game takes precedence. I will get this information to Qv ASAP to get it corrected. Sorry for the misinformation!

No problem, it should be fixed now. Sorry again for the problem and thanks for bearing with us! Have a great day!
