Valve might continue the Quarteros Curios: the reason has been named

Valve might extend the Curiosities of Quarerro event, just like they did with Crownfall, to give players more time to collect all the rewards.

This assumption was shared by dataminer Fay in his Telegram channel.

"I read a comment and thought, that Valve really could say that many players didn’t have enough time to get all the rewards, so they are extending Quarerro"

The analyst also found it strange that in a small Dota 2 update, the event’s background moved to the main menu, if a new event was already planned. Considering this, it’s not impossible that on November 5, when the event is supposed to end, the developer might announce its extension.

It’s worth noting that a similar thing already happend with Crownfall, when the event was extended for several months. This was explained by the fact, that many players asked for more time to collect all rewards.

Earlier, Valve also released an unusual update for Dota 2.
