Blood Thief Queen (Spectre) Unavailable to use

Honestly, I don’t know why the Spectre Blood Thief Queen can no longer be used. I’ve previously used the **Spectre Blood Thief Bug minion, and it worked quite well.

Right now, I really hope to be able to use it again for utility purposes in the build I’m currently playing.

Does anyone happen to know any information about this monster — why it’s no longer usable? Or perhaps the bug issue has been fixed or will be fixed soon so it can be used again?

It was change with the last patch.

"The Bloodthief Queen Monster can no longer be Tamed or bound as a Spectre."
