Issue description

I am trying to create a "public" enum that is accessible in multiple scripts.
Therefore I created a script "Enums.gd"

This contains my Enum I want to use in different other scripts

enum StoryTriggerCondition {
	default,
	pickup_coin,
	kill_chilli,
	talk_to_B_urrito,
	talk_to_Patua_Pechos,
}

I e.g. use it in my "StoryBlock.gd" Script and preload it like this:

extends Resource
class_name StoryBlock

const ENUMS = preload("res://Scripts/Enums.gd")

export(Array, ENUMS.StoryTriggerCondition) var conditions

If I then create a instance of my Resource it works as I expect it to do:

However,after restarting the Editor it looks like this:

The fix is to force reload the depending "StoryBlock.gd" Script like this:

Steps to reproduce

As described above. I have stripped down my project as far as I could before it stops working. I really can't tell what the issue is with it.

Minimal reproduction project

I created a minimal "reproduction" project. However in that it is working without any issues. I can't tell where the issue is coming from.

Is the topic:mono label correct? This seems unrelated to C#.

It's a problem with GDScript. Nothing to do with mono or the mono version of the editor.
