Problem when editing attachments on a message that has been crossposted from an Announcement Channel

[Alex1304]

Description

Updating an attachment on a message that has been crossposted will not show the new attachment in other servers

Steps to Reproduce

• Create an Announcement Channel
• Follow the Announcement Channel in a different channel/server
• In the Announcement Channel, send a message via the API with a Bot user that contains an attachment
• Crosspost/Publish the message (manually or via the API, doesn't matter)
• Send a Message Edit request where you will upload a different attachment overriding the old one

Expected Behavior

The message should be edited the same way both in the Announcement Channel and in the servers that follow it

Current Behavior

The attachment will be properly updated in the Announcement Channel, but in other servers it will still display the old attachment

Screenshots/Videos

Embed in the Announcement Channel that contains the new attachment (note: I'm using the attachment:// technique here on the thumbnail field, but I think that doesn't matter):

Embed in the server following the channel which still shows the old attachment after edit:

Client and System Information

Discord4J library v3.2.6 which still uses Discord API v8 (although the root issue seems to be in the process that edits crossposted messages so I'm not sure the version is relevant here).

It seems this bug cannot be reproduced anymore as of today, has it actually been fixed? Waiting for an official reply before closing the issue.
