Happy you enjoy it. You're right that it's a bit confusing, but we don't want to annoy the players with "unlock the game on patreon to access this content" type of messages. It sounds too much like a gacha or free to play games and is immersion breaking. The free version is just a demo for the full game. You can find which quest is in the patreon version here: https://priceforfreedom.net/avarice/walkthrough
