I got that free gronicicle from that ice storm island quest. The next time I opened up the game, I couldn't find my gronicicle anywhere on the my dragons page. I found it when I clicked my profile, but I could only visit it in stable, and even then, I couldn't see it anywhere! Someone please tell me why this is happening!!
Do you have an empty stable for it? if it does not have a stable, you can't make it active.
