Killer Wisps still spawn in Infinite mode despite none of the associated story events ever happening, although the manner in which they spawn seems a bit... broken? They only start spawning at 00:00 every night, and they seem to stop spawning early if the game is reloaded at any point after they start spawning.
Recently got the "Object in the woods" "the hole" and "where do you think you're going?" achievements when going to Bravo and Xray respectively (can't remember which dish i went to when i got the object in the woods achievement.) I'm not entirely sure if this is a bug or not, but i got them at seemingly random.
Don't know if it's fixed in the new test build, but at least on 0.8.2b the hiking boots randomly partially stop working. It still lets you climb steep hills and ledges without slipping, but the small increase to the height you can fall from stops working, unless I misremember it doing that. I was unable to reproduce the secondary bug so it either was some sort of freak bug that almost never happens or it was caused by something else that happened between when I last ragdolled from hitting the ground and when I next should have ragdolled from hitting the ground, and I just so happened to get the hiking boots between those two moments. So not sure how to reproduce the bug that causes me to be immune to ragdolling from heights.
Either the climb or the stuck inside wall detection has been updated in 0.8.2 and it is triggering the inside wall detection a lot. Even just climbing out of the dips in the vents triggers it, and it triggers instantaneously. I've had it trigger like 10 times just trying to climb stuff inside the base so far.
