Going forward, additional forms of earning tokens will be needed. Including an open, recurring activity that isn't tied to any of the plot lines or the status of any of the areas would likely be a good idea. Alternatively, the corrupted critters need to drop enough tokens that one can afford to recharge what was spent purifying them.
For those who are stuck, here are some good things to know:
1) After the attack of the WAR at the end of your first cycle, you need to progress the plot with Hazel to get the recipe for Black Sugar, collect the ingredients for Black Sugar, make it (at the desk in your cabin), and then you can give it your friends by selecting re-introduce, which will allow you to resume where you left off with them. Otherwise, nothing happens when you try to re-introduce yourself.
2) Once you are asked to find a diary (Not a spellbook; that doesn't exist. Yet, anyway.), you need to go to the center area, where the evening campfire you eat dinner around is found, and move the mouse around the area to the right of the outhouse, above the bush there, until you see a decent sized white arrow pointing behind the outhouse. This only appears after you've been asked to find the diary. I believe it goes away after the related quest is completed or failed. Clicking on the arrow gets you behind the bathrooms, where you will find some trash cans, one of which contains the diary. NOTE: if you work with the quest giver again before getting the diary, the quest is failed.
3) To find the make-up box after you've been asked to do so, you need to explore the forest to find it. If RNG is giving you trouble, you can soft save scum by scrolling up on your mouse to back up, clicking an arrow to go elsewhere, then trying again. NOTE: just as with the diary, if you work with the quest giver again before you find it, the quest will be failed.
Haven't found the key for the chest yet, I'll make an addition if I do figure that out.
