Top Fixes:

• Fixed KIM Ranks changing significantly after playing newly-recovered conversations.
  • Those affected by this issue should see their Ranks restored to pre-Update 41.1.0 status. 
  • Recovered conversations will remain but your rank will not change if you decide to engage with them.
    • Note: Console players will see their Rank briefly change in KIM but it will be restored immediately upon completing a mission, relogging, etc. —  this is only a visual bug that unfortunately requires Code to fix.  
  • This issue was introduced as a fix for those skipping ranks in The Devil’s Triad, locking them out of the (Spoiler) Reunion. Unfortunately, it had unintended effects and we apologize for the state that this fix shipped in. 
• Fixed being unable to remove unique Deluxe Attachments (ex: Kullervo Apostate’s Shoulder Spikes) on a Config if you purchased the skin via the Arsenal on that Config.
  • This fix does not address players already in this state, but you should be able to remove the attachment if you use a different Config.
• Fixed the Dagath Yfari Skin not using custom Kaithe VFX when casting Rakhali's Cavalry.

Vauban Changes and Fixes:

• Missed Note from 41.1.0: 
  • Vauban's Ability Projectiles now take his velocity into account when thrown. This way, when moving quickly on land or in the air, they will no longer lag behind him.
• Removed the bright flash VFX from Vauban’s Photon Strike as it could cause photosensitivity issues.
• Fixed Vauban's Tether-Flechette being instantly destroyed if cast with Vazarin's Guardian Shell active.
• Fixes towards Tether-Flechette's projectiles missing the shake FX following Vauban's Minelayer changes.
• Fixed enemies appearing to fight gravity as they are pulled towards Vauban's Tether-Flechette mine.
• Fixed Sparring weapons appearing invisible when equipped on Vauban Prime.
• Fixed a script error caused by Vauban's Bastille.
• Fixed a script error caused by Vauban's Tesla Nervos.
• Fixed a script error caused by the Tether-Flechette mine from Vauban's Minelayer.
