This happened me in the ruins after changing room. I'm with a torch but the screen is black. Also no charlie warning, so it's not darkness.
The map was strange too, idk if is working as intended.
And a few things more:
-When i pick up poop with bad smell (with flies) in the Pig Village the sound of the flies keep going near the house even if the poop is not there.
-The mechanism for entering in the ruins placing things in the floor is a bit awkward and the rock usually keeps going up and down even if i don't touch the button in the floor.
-Keep one eye on the pig guards. If i attack them and they are with torchs they usually set theVillage on fire and that's not fun. They should change to their weapon.
It was just in day one. I explored the biomes near the spawn and I found the Pig Village, then the next day i keep exploring and found an entrance to the ruins. Before I go in I feed a dog? with monster meat. Once inside i pick some grass and enter in a room in the left, then i take some damage because of the darts traps and with the help of the dog i kill two bats. Then i leave and come back in the main entrance and there's the black screen. I hope is useful guys.
