what I did:

• right clicked a stack consisting of more than one bottle with cork
• with a full inventory

what I expected:

• since the bottle stack isn't finished yet, with nowhere to put the aura bottle, it'd spit out onto the ground
• the final bottle, when clicked, would turn into an aura bottle

what I got:

• with more bottles left in the stack and nowhere to put the aura bottle, the bottle was deleted entirely (bug)
• the final bottle, when clicked, gets turned into the aura bottle just fine (expected)
