Lvl 90 went down, didn't count, and isn't on the summon list

[Phelpsy]

Can anyone help?

Also isn't in the recent boss list either

Same thing just happened to my faction with boss 120, it disappeared and isn't available to summon. I'm sure we didn't finish it yet when it disappeared. Hoping it shows up when the time runs out on it.
