Invalid boolean error.

[CoxinhaDev]

Describe the bug

Whenever I attempt to open a specific file, it simply gives an invalid boolean error and doesn't open the file.

Worked with previous versions of the game (0.42), and whenever I open the game through UMT, I get both of these errors before the game starts normally.

Reproducing steps

1. Open the file.
2. Recieve Error.

Setup Details

1. UMT 0.8.3.0
2. Win 10.
3. Lotty's Adventure v0.43 (NSFW)
