#load directive not working with relative paths

[DT]

Describe the bug

The C# script #load directive does not seem to be able to find files correctly in scripts unless those scripts were loaded with said directive.

Reproducing steps

1. Create a new main.csx file, and paste in the following code:

#load "sub.csx"
ScriptMessage(message);

2. Create a new sub.csx file in the same folder as the main.csx file, and paste in the following code:

string message = "Hello world!";

3. Run main.csx through UndertaleModTool (expected result should be a message box that says "Hello world!", instead it should error saying it was unable to find the file)

In order for #load to start working properly, the script must be loaded from #load using an absolute path, testing this is as follows:

1. Create a new fix.csx file
2. Put #load <path> in the file, replacing <path> with the absolute path to the main.csx file in quotes
3. Run fix.csx through UndertaleModTool, should run fine

Setup Details

I am running UndertaleModTool bleeding edge on Windows 11.
