July 2 Update
Valorant's director Joe Ziegler announced on Twitter that the glitch had been fixed and that Haven was available again in the map pool of ranked games.
It's an announcement that doesn't go unnoticed. Haven is no longer available in the Valorant map pool. The publisher announced that the map, which has three bomb sites, won't be available until further notice because of an identified glitch.
The glitch is about Reyna and her ultimate. Using Empress, she can cross the metal platform present on the C site bomb on Haven. What's most problematic is that she can plant the spike inside this normally inaccessible scenery element...
It's impossible for the enemy team to defuse the explosive once it's planted, which "offers" a round to the team using this glitch. A huge advantage for the attackers who made the publisher react quickly.
There is only one way to counter this: use the same bug with your own Reyna to cross the famous platform and get access to the spike.
No return date has been announced at this time. However, given Riot Games' reaction, it's highly likely that Haven will return to the pool soon, especially since Valorant has only four maps in total.
