I cant progress in the Tricia Story after i talked to Rick and made him make me the purple potion. When i click on the potion after the event with Stacy it says something like "the potion is empty, maybe i used it up with tricia last time". Then he asks Rick to make a new badge and the event with Mortricia starts. :/ I would very much like to progress the Tricia Story. I started over with a new game multiple times and only played the Tricia part, but cant progress past the purple potion event. Can anyone help?
