Some much anticipated fixes for the Adler Limited-Time Event are the highlight of this update, as players reported hiccups while trying to complete it. Intel sometimes spawned outside of the main map, the quest tracker didn’t function properly and a lot of other misbehaviors. With this April 28 update, it seems that everything should be back to normal, although there is little time left to actually complete the full event. On that note, Raven Software mentioned the following:

Although the #Warzone Hunt for Adler event issues have been addressed, we realize that little time remains. We’d like to give everyone ample opportunity to complete their Challenges! We’re considering several options and will update you soon.”

In regards to this, it seems we are getting another announcement pretty soon, for those that were unable to actually finish the event in time due to the amount of issues it had. Stay tuned for more to come. For the time being, let’s take a look at the full patch notes list for April 28 update in Warzone.
