Lost all spectres after logging in

Hi,
today when I logged into the game, all of my spectres were gone. None of them were summoned anymore. Even my auras were turned off, which makes me think that something bugged or glitched.
Yesterday, when I logged out, everything was completely normal and all spectres were still active.
Because of this, I lost: Perfect Forest Tiger, Perfect Guardian Turtle and Perfect Warlord.

same happened to me today
