It may be a timing issue. I found attachments under user 0 and some users complains about loosing attachments.
I tried different ways to recreate it with single upploads but was not successful recreating the problem.
At one occation the username was lost and the attachment was saved under user 0 but still accessible.
1 So I did set the upload to 10 at a time.
2 Created a thread and uploaded 10, (1-10) saved the thread.
3 Edited and uploaded 10 more (11-20), saved the thread.
4 Edited again and uploaded 10 more (21-30), saved the thread.
5 Edited and uploaded 10 more (31-40), then uploaded 10 more (41-50) before leaving the attachment upload window, saved the thread.
Then the first uppload (31-40) was lost when saving.
6 Edited again and saved and now the (41-50) appeared under user 0.

Another way I found on a 3.5.4 Forum was if you create a new thread and change the user, write the post, upload an attachment and save, then the attachment was lost. Since this was some time ago I do not recall if it was saved under the wrong user or user 0.
After I discovered the problem I just changed the way I used the hack and changed the name afterwards instead.
May be a related problem to the above.

PHP 4.4.2
Zend Engine v1.3.0
ionCube PHP Loader v3.1.16
Zend Extension Manager v1.0.9
Zend Optimizer v2.6.2
MySQL 4.1.21-standard

Hope this may help,
Many thanks for your excellent Mods and your way of supporting them and taking time to investigate issues like this.
