Changes:

• Restored controller Action Sets in the Steam Input Configs. 
  • We made a mistake in yesterday's update when we removed Action Sets without warning and we deeply apologize to the Tenno who rely on them to make Warframe more accessible on controllers. Our goal moving forward is to work towards better support of our default config, especially for the purposes of making Warframe more accessible. So we thank you for all of the very informative comments and discussions on the subject, as they are extremely helpful towards that goal. We encourage you to continue to share in the PSA thread. 
  • When controller action sets were removed, it likely cleared players’ custom configs as well. This means that once the Hotfix goes live, players will need to manually set them up again as desired. We’re deeply sorry for the continued inconvenience! 
  • In the midst of restoring Action Sets, we have also made the following fixes: 
    • Fixed adaptive triggers not working with Steam Input enabled. If you wish to disable/enable haptic feedback, you can do so by going into settings in Warframe > Controller tab > scroll down to Gameplay settings section > Use the “Enable Controller Trigger Effect” toggle. 
    • Fixed being unable to use Transference and Last Gasp by pressing the touchpad on PlayStation controllers both when “Use defaults” in the Warframe Steam Input Configs are enabled or disabled.
  • Certain issues that were fixed with the removal of action sets will be reintroduced. These have been persistent issues with Steam Input Action Sets, and we do not have an estimated timeline to address them at time of writing. The following lists some of the issues, but is not exhaustive and you may encounter others. 
    • Kahl’s jetpack boosters can get stuck always activating. 
    • Necramech’s stamina stuck continuously draining after dodging/dashing repeatedly. 
    • Backing out of Pilot/Gunner seats in Railjack is bound to Square/X, which nullifies the Flush Heat Sinks Intrinsic reloading mechanic. 
    • Archwing cannot utilize the blink mechanic. 
    • Held inputs remain intact after the Ability menu is opened and closed. 
  • For peace of mind, the following fixes/improvements that occurred after yesterday’s update will remain in place post-Hotfix:
    • Full keyboard & mouse support for Steam Deck and Steam Big picture mode. 
    • The “Enable Controller Trigger Effect Function” toggle for DualSense Controllers remains restored. 
    • DualSense LED functions remain restored. 
    • Controller icons auto-detection when set to default remains restored. 
• Removed the ability to replay the Chimera Prologue, Erra, and Heart of Deimos quests. 
  • Quite a few issues have popped up for players when attempting to replay these quests, so we'll fix those behind the scenes and enable replay when they're more stable.
  • Note: this has no impact on Tenno who are playing these quests for the first time!
• The Alerts tab in the Navigation window will now prioritize time-limited events like Gift of the Lotus Alerts above the recurring weekly Alerts (Ayatan Hunt and Help Clem) to increase their visibility.
