In the sewers, I got the wheel died and reloaded and the wheel was neither in my inventory nor where it should have been in the reloaded save.
In the school, the library door is interactable but doesn't display it (i.e. doesn't tell me to press e).
thanks for the detailed report, Kurruja, I'll pass both of these along to the team so we can take a closer look and get them fixed up. <3
