Two Questions: Saves and RAM

[SilasMortimer]

I'm not really having any issues running the game, but these are technical questions and I'm using the Linux port, so this seemed the most likely subforum to post under.

1. Saves

I am baffled regarding how saving the game works. This might actually be an issue, but it might just be the way it's supposed to go. I don't mind when I load up the game and it puts me a little before where I ended my last session, but when I load up to find that it puts me only halfway through the progress I made in the entire last session, it's disconcerting and disappointing.

The most recent example of this: When I had last done a "save and exit", I had just gotten inside of Omicron, the main building. When I hit "continue" the next time, it loads up me up in the crawlspace in Theta after losing the DUNBAT and before finding the ARK prototype.

Was that supposed to happen? Was there no point further along where it could have loaded me?

2. RAM

I love the seamless transitions between scenes with no loading screens. I'm guessing this is why SOMA takes up so much RAM. Still, it's a little surprising to me how much it takes up. Have other Linux users noticed this? Does anyone know if it does the same in Windows and Mac? It's not really that big of a deal, but I'm curious.
