No idea if this is a bug, but when I went away to go mining, my plants started to wither away. So I reloaded the save prior to where I went exploring and stayed with the plants instead and they didn't wither away. Seems like if you have to stay really close by your plants when you grow them, or else they wither. I feel like this must be a bug, as it has only happened twice, but still annoying since I have to reload a save and lose all my mining progress.
Another "fun" bug I had was that if I deleted the "save game" button, you can't save your game anymore unless you close down your game and reload a save. Maybe put an option so you can't delete the "save game" button! :)
Otherwise, loving the game so far!!! :)
