Character's spirit halved

https://youtu.be/eApwg_0jqE8

Oracle level 91 with 100 spirit from campaign + 46 from body armour + 48 from amulet for a total of 194.

After entering a map my spirit went down to 97 and my auras deactivated.

If I enable one 30 spirit aura without any supports the spirit goes from 97/97 to 37/97.
If I take off the 46 spirit body armour, max spirit goes down from 97 to 74. Further taking off the amulet lowers it to 50 spirit and no auras can be activated:
100 spirit Eternal Rage: "100 Spirit required to use (Current Spirit: 50)"
30 spirit Savage Fury/Herald of Ice: "Not enough spirit"

Doesn't help:
* going in and out of a map
* going to a campaign area
* going back to character select
* creating a new character
* restarting the game
* refunding a passive
