Fortnite Update 12.50 will arrive this week, according to Fortnite data miner and Twitter user @ShiinaBR.
Epic Games has left the contents of Fortnite Update 12.50 unconfirmed outside of a bug fix for Sky's "Block damage with a Kingsman" challenge failing to track progress.
Epic Games originally planned to end Fortnite Chapter 2 Season 2 on April 30, likely in the same update window it will now use for Fortnite Update 12.50. The developer announced it would extend Season 2 — thereby delaying Season 3 — in an April 14 developer blog post. Season 3 is now scheduled to arrive June 4, more than a month later.
Epic Games did not provide an explanation for the delay.
