Hello Tenno! We wanted to get out some important fixes before the team takes off on a Canadian holiday long weekend. Take care! 

Changes:

• Made improvements to the objective marker pathing and visibility in the Corpus Outpost tileset. 

Fixes: 

• Fixed the Okina Evolution 3 Incarnon Challenge not progressing. 
• Fixed Caliban’s Summulyst not summoning Choralysts in Exterminate missions.
• Fixed Koumei’s Kumihimo strings not spawning correctly when cast in Frost’s Snowglobe. 
• Fixed Arcanes unequipping after exiting the Arcane selection screen in the Loadout Navigation UI. 
• Fixed a duplicate version of Client Warframes appearing when returning to Dry Dock from a Railjack mission. Spooky season may be upon us, but doppelgangers be gone!
• Fixed Kalymos slip sliding around in The Lotus Eaters Quest. 
• Fixed Loid being incorrectly lit in sections of the Whispers in the Walls Quest. 
• More fixes towards a t-posing clone appearing on full-body FX —  notably, the Temporal Prime Ephemera.
• Fixed shading issues on some parts of the Lumis Liset Skin. 
• Fixed being unable to search unowned Mods in the Codex based on their description. 
• Fixed the end of mission UI showing that Beast Claws gained Affinity when they are already max rank. 
• Fixed a rare bug that allowed Helminth to add Eclipse, Roar or Xata's Whispers onto Chroma, Mirage, Rhino, Octavia and Xaku in addition to their own damage boosting abilities.
  • It is intended that the aforementioned abilities can only replace those Warframes' respective damage-boosting abilities (ex: Roar can only replace Vex Armor). Accounts with affected Warframes have had these listed abilities reverted.
• Fixed Nova’s Molecular Prime not using the correct explosion sound FX. 
• Fixed crash caused by searching Captura Scenes in the Arsenal. 
• Fixed script error caused by Nova’s Wormhole.
