Windows 10, 16GB RAM and I have 3 saves. I deleted two of them, because they was somehow corrupted and still crushes. Then I made two new ones, so I keep them 3 so far and the game continues without crushes now, but I still experience the long loading about 5-10 minutes and even when I want to save the game it takes about 5 seconds to load the save game screen. This two things (save and load) constantly slowing down as the game progress, even though I have a pretty strong PC
edit: right now, the current save have around 75 days played, I'm on the step 8 in church and when I tried to load the game, I was waiting more than 20 minutes and the game was still not loaded, so I gave up
I also tried to create a new game and it loaded right away, so it seems like the more progress you have or more scenes you seen in the game, the more you'll have to wait to load
edit2: I tried it again, but even after 2 hours, the game save didn't load :/
