Spirit calculation

Hello,

I have 259 spirit but I can allocate at the same time :

- Herald of thunder (30 spirit)
- Combat Frenzy (30) - Precision (10)
- Trinity (100) - Cannibalism (15) + Vitality (20)
- Wind dancer (30)
- Ghost Dance (30)

for a total of 265.

However, if I deactivate Trinity, I can not activate it and got the message "Not enough spirit". If I take off vitality for example, I can not put it into trinity again, but I can if I deactivate one of others aura (Combat frenzy for example), put vitality into trinity, and then activate agacin Combat frenzy.

If I deactivate an other active gem (HoT, Combat, Wind or Ghost dance), I can reactivate it without any problems.

Thanks.
