DepthOfFire,
Sorry to hear you're having this issue. Were you trying to save while in the Forest, by chance? Saving is disabled in the forest, to stop players from trivializing the RNG via save-scumming.
Thanks for playing my game, and I hope you're enjoying yourself so far.
I'm sure you'll be pleased to know that as of update 1.0.1, we have added a warning at the the edge of the forest that informs the player they will not be able to save once they are inside the forest. Your thread here was no small part in motivating that change to happen. It's not flattery to say that Perils of Aestus Forest is now a better game because you brought this issue to our attention.
Thank you so much for your feedback.
