DrawImageRect: Image does not exist

#1
Walked into SCP 372's room, read the text on the monitor and got a red error on my screen. (I don't remember what it said)
After that, all boxes in the menu and in my inventory were a weird white texture, and the text inside them only appeared when I hovered over them.

The error log I got after closing the game was filled with the line "DrawImageRect: Image does not exist" repeated over and over again.
