Stack overflow while tmp font override is on

[Shamer6246]

I'm using this mod for replace tmp font only, and the game is Limbus Company.

While override is on, the game keeps throwing '[Error : Unity] NullReferenceException: Object reference not set to an instance of an object.' error on title screen (after tmp text appear), and stack overflow will happen on main menu, causing the game to crash.

Override itself works fine (the font is replace and display correctly), and using tmp fallback font won't cause this problem.

Here is the logs:
