Encountered 2 game breaking bugs so far. The first is during the ghost quest. If you interact with the seal inside the portal from the southern square and try to save or step back, you get locked up, I assume because there's nowhere to 'back up' to since your back is to a wall. I had to put in a cheat plugin that turns on noclip so I could 'back up' in order to progress.
The second, I encountered a bug where when I passed out while mining, my toolbox disappeared entirely. Quitting and reloading, sleeping, nor restarting the game helped, I had to load an earlier save with a non-bugged toolbox. Additionally when I tried quitting and reloading, all my unwatered crops mysteriously disappeared.
Edit: I had to put this game down. I went through the annoying red forest section where the encounter rate seems outrageously high and when I finished it and returned back to the village, the game crashed. My last save was about an hour ago.
