[Bug] Treated like cattle - 2nd potion does not work

[Boink]

As title.

Found x1 potion, gave it to Mabel, asked for no reward.

Deciphered book, made a 2nd potion, gave to Geradline - chose the "feed her the potion" line.

Got a response "This will take a minute to kick in" and the conversation ends, but nothing happens. Now, when talking to her I get the same options even without a potion in my back-pack.

Bugged.

Same. The crafted potion is never removed from my inventory. Tried asking for reward and not with no change.
