Updating Files with InteractionRespond will not delete old or existing files

[Janvos2506]

Hi,

I am trying to update the image in an embed. The behaviour I'm seeing is not what I was expecting, please see MVP down below.

When executing the component via the button click it calls InteractionRespond with InteractionResponseUpdateMessage. In this update I assign a new Files array with a new image. I also update the included Embed. I expected this to delete the previous image and load the new one. But what actually happens is it updates the embed but leaves the attached image hanging, please see the screenshot.

//Triggered by /PlayGame

err = s.InteractionRespond(i.Interaction, &discordgo.InteractionResponse{
	Type: discordgo.InteractionResponseChannelMessageWithSource,
	Data: &discordgo.InteractionResponseData{
		Embeds:     []*discordgo.MessageEmbed{&discordgo.MessageEmbed{
				Title:       "Map",
				Description: "map"
				Color:       0x00ff00,
				Image: &discordgo.MessageEmbedImage{
					URL:    "attachment://Map.png",
					Width:  512,
					Height: 512,
				},
			}
		},
		Flags:      discordgo.MessageFlagsEphemeral,
		Files: []*discordgo.File {
			{Name: "Map.png", ContentType: "image/png", Reader: r},
		 },
	},
})

//Triggerd by the button click via component
r := //Get bytes of image...
err = s.InteractionRespond(i.Interaction, &discordgo.InteractionResponse {
    Type: discordgo.InteractionResponseChannelMessageWithSource,
	Data: &discordgo.InteractionResponseData{
		Embeds:     []*discordgo.MessageEmbed{&discordgo.MessageEmbed{
				Title:       "Other Map",
				Description: "different map"
				Color:       0x00ff00,
				Image: &discordgo.MessageEmbedImage{
					URL:    "attachment://differentMap.png",
					Width:  512,
					Height: 512,
				},
			}
		},
		Flags:      discordgo.MessageFlagsEphemeral,
		Files: []*discordgo.File {
			{Name: "differentMap.png", ContentType: "image/png", Reader: r},
		 },
	},
})

This looks good

Here the old map stays put and is being rendered outside of its embed?

What is going on here? Am I handling this scenario correctly or is there a better way?
Thanks
