Each time I load a save, the game consumes more and more RAM. For example, after the initial load the process is at 4.5 GB, after the second load it goes to 6 GB, then 7 GB and so on. It happens both when loading saves from the pause menu and when exiting to the main menu and then loading a save. The memory consumption doesn't go down, so after a few reloads OS just kills the process.
Workaround: I just hit Alt+F4 and open the game again every time I want to load a save.
1. Load attached save.
2. Go to step 1.
