TL;DR
Warframe: Hotfix 12.2.1 fixed several issues, including Void Keys still appearing as rewards in some higher-tier Void missions, Legendary Cores not always fusing Mods to maximum level, Legendary Cores being consumed by Auto Fusion, and the Enter key failing when sending Clan invitations.
What Changed
- Fixed Void Keys still appearing as rewards in a few higher-tier Void missions.
- Fixed Legendary Cores not fusing Mods to maximum level in some situations.
- Fixed Legendary Cores being consumed by Auto Fusion.
- Fixed the Enter key not functioning when attempting to send Clan invitations.
- The notes also say Legendary Cores should now be distributed to all qualifying players.
Player Impact
Players running higher-tier Void missions should no longer see Void Keys as rewards in the affected cases. Legendary Core behavior was corrected so they should now fully rank Mods when used, and they should no longer be consumed by Auto Fusion. Clan invitation sending should also work properly with the Enter key again.
