Might have hit a bug.
Got the sleeping potion for Bert. However I'm unable to get beer from the tavern. There is no option to get it. I had the option earlier when playing and have the option to give Bert things. But no way to get the beer and it's not in my inventory.
Am I just missing something or bug?
Either you have an empty beer mug in your inventory, or there is a bug. If there are no mugs in your inventory, then send the save to the author of the game. https://townofmagic.com/contact/
