The advancement "Little Sniffs", that should only be obtained after a snifflet is fed Torchflower Seeds, can be also obtained by simply unleashing a snifflet while just holding Torchflower Seeds, without it actually consuming it. Similar problem also occurs with the advancements "Shear Brilliance" and "Isn't It Scute?" using the unleashing method.
What I expected to happen was...:
Only unleashing the snifflet.
What actually happened was...:
I also got the advancement "Little Sniffs".
Steps to Reproduce:
1. Leash a snifflet;
2. Hold Torchflower Seeds;
3. Right-click the snifflet to unleash it.
