iOS Specific Fixes:

• Fixed players on 4GB RAM devices seeing a black screen when they tried to enter Duviri by tapping the mask icon on the Star Chart. 
• Fixed touching multiple Platinum options in the Market at the same time resulting in a loss of function. 
• Fixed being able to move around while in Mesa’s Peacemaker without Mesa’s Waltz equipped. She’s taking “Warframe Mobile” a little too seriously here!
• Fixed broken UI when selecting an Alert on a locked node. 
• Fixed Orb Vallis missing Alert Level HUD elements next to the minimap. 
• Fixed 3GB RAM devices being able to access Duviri Open Landscape when the content is not optimized for their devices. 
  • Vox Solaris, Cambion Drift, and Duviri can cause devices with 3GB of RAM to crash. As such, these areas were restricted on those devices in 2024. 
    • The Duviri Landscape accidentally became accessible on 3GB RAM devices, but is still not optimized for these devices. It has been restricted on these devices once again to prevent crashing. 
• Fixed Gear Wheel touch control only being able to summon the Atomicycle (instead of accessing the Hear wheel) if the Atomicycle Summon is equipped and then used in-mission. 
  • Also fixed being unable to access the full Gear Wheel (instead of being restricted only to the Atomicycle Summon) in a certain stage of the Hex Quest. 

Changes:

• Ember and Frost’s passives now apply to their Affinity Range, instead of being a fixed range. 
• Disabled use of the Atomicycle in all Warframe Quests -- excluding The Hex Quest, of course!
  • While we are committed to keeping the Atomicycle where we can outside of 1999, it was causing numerous Quest cinematics to break if you were on wheels. It’s important to us to preserve and protect these cinematic Quest experiences — apologies!
• Updated Arcane Camisado's description to indicate that the buff only applies to the next Ability cast, then resets.

1999 Changes & Fixes:

• Increased the explosion radius of the "Techrot enemies explode on death" modifier in Höllvania Bounties. 
  • The original radius was quite small, making it seem like this Bounty modifier wasn’t working. Now you’ll have to stand a little further away if you want to avoid getting Techrot goo on your face!
• Once you complete all months in a 1999 Calendar Season, the sidebar in the Calendar screen will now indicate how long until the next season. 
• Fixed the Backroom node appearing as incomplete in the Steel Path Höllvania NavNow screen. 
• Fixed agreeing to Date a Protoframe while Best Friends resulting in your Chemistry Rank not changing (and related mechanics not triggering). 
  • Those who were in this state prior to this Hotfix will need to earn Chemistry with said Protoframe (via gifting or Bounties) to get their rank to update.
  • Also fixes the same issue if breaking up with a Protoframe. 
• Fixed Faceoff Assassination targets not being flagged as VIP units, meaning they were able to be trivialized by various Warframe Abilities. 
• Fixed placing Decorations in the Backroom not counting towards The Personal Touch Nightwave Act. 
• Fixed the "Profile" button in the KIM screen not being localized.
• Fixed a player response to Amir not being localized in KIM.
• Fixed loss of function when clicking on the Profile button in KIM on the Turkish client. 
• Fixed an Ordis voice line playing while removing a Helminth Cyst in the Backroom. 
• Fixed 1999 Calendar date change SFX not respecting sound settings.
• Fixed being able to use your Operator in Höllvania Central Mall. 

Fixes:

• Fixed Eximus spawning at an increased rate in the Origin System
  • Missions in Höllvania have these increased Eximus spawns, but it was also unintentionally applied to normal Warframe missions!
• Fixed performance issues related to Arcane Camisado. 
• Fixed Companions not dying after triggering Sacrifice and Martyr Symbiosis if they have Overguard. 
• Fixed Cyte-09’s Neutralizer not being affected by many sources of Ability Strength (i.e. Precision Intensify, Energy Conversion, etc.). 
• Fixed bonus Invisibility duration from Cyte-09's Evade not properly applying to Clients.
• Fixed bonus Heat Procs from Reconifex and Cyte-09's Resupply not stacking properly.
• Fixed Physical Status types no longer triggering Arcane Cascadia Empowered. 
• Fixed all mission nodes disappearing if selecting "Change Loadout" in the Navigation Screen when the player only has one Loadout.
• Fixed Signas persisting when swapping between Appearance Configs using Gemini emotes in-mission.
• Fixed dark VFX appearing on Gemini Skin faces when used with the Seraphayre, Tenebrous, Raptwing, and Protovyre Ephemeras.
• Fixed a certain character standing during a section of The Second Dream Quest. 
• Fixed the Pom-2 appearing in the Orbiter during The New War Quest. 
• Fixed Quincy having a robotic voice in one of his Gemini Skin voice lines.
• Fixed Somachord music playing in the Prime Resurgence screen if accessed via the Market.
• Fixed a crash caused by the Mandonel. 
• Fixed a script error caused by Revenant’s Mesmer Skin.
