My mouse double clicks regulary and it's breaking the game. I want to press Explore, it click on Explore and Examine. Sometimes it makes the whole room to call out, it returns after entering a dungeon. Once it made my character to move to the middle of the room. But usually it makes the screen fully black with no any visible UI.

Infection progress has the opposite effect on hunger than is expected. The random drug encounter describes you as (paraphrased) "extremely hungry as the infection converts all food into fluid". The same is noted in the examine self text.

Instead when you are low on infection at the start of the game you will starve in ~24 hours, but get to 75% infection and you can go 5-6 days without eating. The start of the game is extremely hard because of this, you need to get infected as fast as possible and then hope you find the elastic medicine.

I don't know exactly what caused it, but after playing for a while as Female A (saving & loading many times) I could not swap characters to Female B when starting a new run. It would just force me into Female A until I closed and opened the game again.

This might be just a balance choice, but it's odd that the breastfeeding woman encounter doesn't restore hunger when you are forced to drink. The Mina encounter does restore hunger, so it just seems inconsistent.

I don't think it's possible to fail at convincing the outskirts man to pump himself. It didn't seem to matter how many times in a row that you fail to convince him, I have never been attacked.

Edit - Fail as in critically fail to the point where he attacks you.

Hunger can go into the negative, especially noticeable with contaminated produce at high infection levels. This is important because of MREs - MREs seem to subtract a set amount from hunger and then set your hunger to zero, giving a ration for every <x>% negative the number is.

When you're at like 120% infection, eating 2 or 3 contaminated produce and then eating an MRE can give 20-30 rations. Then you can reduce your infection with drugs and be able to survive a long time off of the newly gained rations. My highest amount obtained this way was getting the "Lick walls in underground base" event, then eating 8 contaminated produce to get 80 rations.

There is a lighting bug when reloading sometimes. When you load, the mountains in the background will be fullbright, the sky will be dark blue, and there is no lights on inside the hut.

I think it's when the game is saved at midnight.

The "Give In" option at the bunker still seems to have a chance of making you look away and go search for items. I'm not using the experimental version at the moment, so I'm not sure if this also happens there.
