I found an older thread that stated the tiny spiderling was initially not in the game until a later fix.

 

However, in my completionist playrthough I found several pets are still missing. Namely the terrier and the tiny sporeling. The prima guide (which I assume is official?) stated they are in the game (next to Gordy in Copperlane and Iswld at the Golden Grove, respectively). But they are not there.

 

Other players have the same problem: here, here and here.

 

Are these similar cases as the spiderling? Will they be added back into the game?

Hello LaSpeakeasi,

 

Thanks for pointing this out. I have written up a bug and added it to our database base.

 

Keep up the good work!
