We've released an emergency hotfix patch.
The NPC hearts were broken in the journal where, if you had gotten heart points with an NPC after the latest patch it would duplicate their name or create a new blank NPC. If that has happened the latest patch should fix that bug, as well as remove the duplicate NPC with the least amount of hearts so you can keep your progress. We also fixed a bug where certain multiplayer quests would crash the server.
Because we are a small team of only two people, sometimes bugs can get overlooked. If you experience any issues caused by the latest patch or at all, please let us know in the steam discussions and we will try to fix it as soon as possible. Thank you again for the support, we hope you enjoy the latest patch.
