Operating System:Windows XP Home
Web Browser:Firefox 19.0

Status: Resolved (498.1169)

This issue has been resolved.
Copied from the Beta Testers forum.

Descriptive Problem Summary: When blocking a user who you have added as a friend, who has also added you as a friend, after chatting via pager with them, results in them being placed in your friends list twice.

Numbered Steps to Reproduce Problem:
1) Ensure that someone has added you as a friend.
2) Add that user as a friend.
3) Send a page to that user and have them reply with a response. (A response may not be necessary.)
4) Unfriend and block that user.
5) Observe their name appearing in the friend's list twice.

Expected Results: For their name to only be listed once.

Actual Results: Their name appears twice (Although one tends to dissipate after some time.)

Does the problem occur:
Every time? Or how often? Every time.
In other games? N/a.
In other user accounts? Yes.
On other computers? Yes.

When does the problem NOT occur? The problem does not occur if they have not added you as a friend or vice versa.

Did the problem NOT occur in any earlier versions? If so, what was the last version that worked? This has occurred since at least version 498.1153 and may have occurred in previous beta versions.

Workarounds: Unknown.

I finally managed to reproduce this, but only with a response. That does appear to be required.
