I assume these missions are special for Halloween as Madame Roget has never had them before.
The Meowling is broken. Tier 2 is to talk to Andy about his cat. No matter how many times you talk to him about kittens nothing happens.
The Cat God is broken. There is no mission marker at all, period, so there is no mission apparently. Guides from years ago say the entrance is in Blue Mountain, but the only thing near the alleged coordinates is a little tunnel in the rock that says you don’t meet requirements to enter, and apparently there should be a portal.
The pale horse tends to go silent, the clip clop of running vanishes randomly.
Flare guns (mission item) don’t work. You can shoot a flare, but it does nothing. See Dawning of an Endless Night where you have to go into the mine shaft. It’s dark down there, no mission marker indicator (another bug), no map (annoying), and the flare gun you stumble across does nothing. So you run around in the dark aimlessly with no sense of direction until finally finding the Guardian and moving forward. Side note, how the heck do you get back outside after the shadows knock you out? Bit of story telling gap there…
I have something called Well-Used Medallion. No idea where it came from, been stuck with it for months. Can’t delete it, can’t sell it, and it’s a useless item (+5 HP neck talisman). This is very annoying taking up space for no reason, and clearly should not be permanent junk in your inventory.
Petitions don’t work well, there is no indication they are ever updated. Most times they are not responded to at all.
New UI bug added in the last update or so, every time you interact with an item you change to mouse mode (as if you hit Alt) and have to hit Esc or Alt to get back game control.
