On April 3, Apex Legends released update 1.1 with massive bugs. Now the developers explain what was the reason for the huge issues.
What happened? On April 3 around 7 PM, patch 1.1 for the battle royale shooter Apex Legends was released. Quality-of-life improvements were planned to enhance the game quality.
Instead, players were surprised to find that all their earned progress was gone. Skins, levels, materials – all deleted. As if it had never been earned. Players were angry.
Apex Legends quickly noticed that something was wrong and took the servers offline in the evening.

They worked for a few hours on a solution and were able to give the green light around 11 PM. The servers are back up, and all players’ progress has been restored.
What caused the chaos of the update? Developers commented on Reddit and wrote:
When update 1.1 was released, players were inadvertently routed to different servers.
This caused it to appear as if the entire account progress was deleted.
The developers then shut down all live servers to prevent players from the wrong servers. Once they were confident the error was fixed, they allowed players back onto the servers, this time on the correct ones.

Items purchased during the time between the first update 1.1 and the subsequent fix were reverted, and the currency for those was refunded. Other progress such as increased levels, unlocked items, or opened packs was also reverted.
What improvements did the update bring? With the new patch, you now have the option to invite players from the last squad into your team in the main menu. Also, there is now a button to mute the music in the intro and during legend selection. All patch notes for update 1.1 of Apex Legends are here.
Accidentally released new feature: Chaos was also caused by a feature that shouldn’t have been released at all. This addresses leavers:
