TL;DR
Warframe Hotfix 12.1.1 fixed a launcher issue that could incorrectly prompt players to update and block logins. It also changed Grinlok’s muzzle flash and sounds.
What Changed
- Fixed an issue where the launcher incorrectly prompted users to update the game, preventing logins.
- Changed Grinlok’s muzzle flash and sounds.
Player Impact
Players who were affected by the launcher bug should now be able to log in normally after the hotfix. The Grinlok audio/visual changes affect how the weapon presents in play, but the evidence does not describe any gameplay or balance changes.
