Private ValueInitializer methods (in some situations?) cause exceptions while wiki gives it as an example

[SokyranTheDragon]

The wiki gives an example of a private ValueInitializer method: https://github.com/Zetrith/Prepatcher/wiki/Adding-fields#default-values

However, doing that seems to cause exceptions (or at least in specific situations). The wiki should likely be updated to give a warning/change the example.

Code that causes issues:

public static class PawnDataUtility
{
    private static PawnDrawData MakeBlankDrawData() => new();

    [PrepatcherField]
    [ValueInitializer(nameof(MakeBlankDrawData))]
    public static ref PawnDrawData GetData(this Pawn key) => ref PrepatcherInactiveFallback(key);
}

Exception:

Error while generating pawn. Rethrowing. Exception: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.MethodAccessException: Method `YayoAnimation.Data.PawnDataUtility.MakeBlankDrawData()' is inaccessible from method `Verse.Pawn..ctor()'
