Ymir's armor set not repairing

Game mode: [Online]
Problem: [Bug]
Region: [Here]

So i got the armor set from the Ymir religion (altar level 2, havnt tried 3 yet). It was damaged and i wanted to repair it with ice shards, and it got stuck on repairing (the rotating gear keeps rotating and no durabillity is added). I have tried putting it in chests and back but even in the chests its still stuck. However, i have left the armor set in the chest and the next day it was suddenly fully repaired. Is this a bug or does it just take really long to repair?

Steps on how to reproduce issue:

  1. Choos ymir religion (perhabs others work too?)
  2. Level up altar to tier 2
  3. Craft the armor set
  4. Try repair it
