Deleting messages sent by a Deleted Account (Deleted User#0000)

[ghost]

Let me preface this by clarifying that I have Admin powers, and am able to manually delete messages that a Deleted User sent in my server.

I am able to retrieve the Author ID for a deleted account. Using this to run the Undiscord script, I come across a problem where the script does not fetch messages linked to the Deleted account. The Grand Total of fetched messages is 0, and the script terminates, even though the Deleted User has clearly sent messages.

When trying to delete an Active account's messages, the script works just fine. This is an issue only with a Deleted account. Using bots to tackle this issue is also unfeasible for me, as a deleted user cannot be @ mentioned.

Can this issue be fixed?
