Spectre's gone twice! - Phrecia

Hi, after summoning my first 3 spectres, I wanted to upgrade the quality of my helm (which wears the spectres gems) knowing that my spectres will just fall dead on the ground and I'll be able to revive them.
Well, only one of the 3 remained on the ground, the rest disappeared.
I tried it once again to make sure and same thing happened.

If spectres were cheap I'd get it but I can't spend at least divine orb each time i have to unequip my helmet for whatever reason.

Is this fixable? It's very annoying.

The corpse item spectres you will loose them I think. Not an expert on this but that might be the difference, where the non itemized ones are retrievable.

It's not terrible the way it is, but it certainly makes playing specters a bit clunky, especially for noob players. Which could be overall a bit more player friendly, since spectres them self are pretty cool to play.

I think that is what they are tying to do with the itemized ones, but its still pretty clunky in my experience as a noob spectre player.
