When making a drink for Aunt a choice is given for if you want to add more alcohol or not. If you select no and return to Aunt there is no option to give her the drink and it just loops back to the starting dialogue and you then have to go back to kitchen to make a drink. This can be repeated forever unless you select to add more alcohol to her drink.
These bugs are from an older version of the game, by now they should be fixed although they have not been tested. Please report them again if they are still present.
