Weird taming experience!

I had a weird experience whilst taming Gondria today.

I came across him at about 5pm near the Altar of Quetz'lun, on a fly around just to see if he was about. *lucky* So of course, I jumped right down, dropped a trap and tamed him. However, after taming he remained huge, the name bar said Gondria not 'spirit beast', and he had no talent tree available o_O I've never experienced this before (not with normal pets or with Arcturis or Loque'nahak).

I really wish I'd taken a picture, as when I logged out and back in later he was shrunk, named spirit beast, and as he should be *boo*.

Anyone else had this happen?
