While playing, the game occasionally stuttered. In task manager, I saw how my RAM was gradually filling up. The first time this happened, I could clear it by tabbing out of Infinitode. However, the second time my PC crashed (probably due to the RAM being completely full). The PC crashed during restarts, and OS recovery didn't help. After cutting power completely, it booted up normally.

As this problem only occurred to me while playing Infinitode 2, I doubt that there is a bug in another application.

To clarify, at the time of playing, I had two tabs of Edge opened on a second screen and steam running with a few other background processes. Maybe 8 out of 16 GB of RAM were in use.
