Hi there !
I started a new save and got to level 1 sneaking (and lightfooted) before the end of day 1 playing normally.
I though it was strange because, the way I play the game, I level sneaking only after some in-game weeks. I did some testing and I was able to get to level 1 sneaking at day 1, in just 3 in-game hours, just by walking in sneak mode inside the starting house without zombies nearby.
The game mode is Apocalypse without any mods --- is this a bug or was the sneaking mechanics changed?
Thank you !
