Problem with disenchanting a dragon?

[G4OU812]

I just finished evolving a dragon (Buttercup) and I can't do it from the Dragon Portal nor from a habitat. Anyone else having a problem disenchanting a dragon? I have other dragons that I evolved previously and they can be disenchanted. I'm not sure if the issue is the Buttercup or something else. I have about 20 minutes left on another dragon to finish evolving and curious to know if I will be able to disenchant it.

Their was a discussion about this a few weeks ago. There are some dragons that can't be disenchanted. Buttercup must be one of them. You can tell beforehand by looking the dragon up in the Codex to see how much Essence it gives.

Okay, thank you for the response.
