I just finally tried dragon breeding today.
Previously I’ve only had the Sicilus dragon from back in January.
I read in the wiki that “Dragons acquired from the Backer tiers of Kickstarter, and Sicilus Beastiary quests can still be used in Dragon Breeding. The first time they are placed in the terrarium they will be assigned traits. These traits will not match the outward appearance of the dragon.”
So I placed him in, closed the lid on the chest, stepped back, then retrieved him. His tooltip didn’t change; still just says Pet with no stats displayed.
Logged out and back in, same.
Bought a tiger dragon from the Zoological gardens. Made sure new dragon was happy with a treat. Fed my original dragon again too.
Put them both in the terrarium, no flame.
Tinkered in my home for a bit, brewed some potions, no change.
Went back to the Zoological gardens and splurged half of my dram to buy a sea dragon.
Came home, fed him, put him in with the new tiger dragon – ah ha, the flame of love!
Started searching the forum, didn’t find anything quite the same. Did find this post from April which at the end has some talk of the Sicilus and Kickstarter dragons having an issue that should have been fixed with a patch around that time.
I think my dragon might be antisocial?
