Forum:Why are my categories being added twice?

The categories on pages I've created recently seem to be magically duplicating themselves. As in, I put the category in ONCE and after I save the page it shows up in the source code TWICE. Once, it got up to four times.

At first I thought maybe a template was to blame, even though categories added via template shouldn't be showing up in the source text at all, and I double checked to be sure all the noincludes and onlyincludes were in the right place. Then it happened again on this page where the category ("Ways to alter your base stats") has nothing to do with any templates. I haven't fixed it yet, so that you can see for yourselves.

Any ideas what's happening? Thanks! Psychoadept (talk) 18:37, August 23, 2012 (UTC)


 * It sounds like it may be a bug. Send this in with Special:Contact.  Love and Lust  18:52, August 23, 2012 (UTC)


 * There used to be a bug similar to this which occurred when pressing the submit button while viewing a preview. I had thought that this was fixed, but maybe it still occurs on some wikis.  Do you use the submit button in the preview popup? -452  01:19, August 24, 2012 (UTC)


 * This is a known bug, however for the most part it is intermittent and rarely seen. Please do send in a report to special:Contact as we can at least track that it is still happening that way.  -- Wendy  (talk ) 02:06, August 24, 2012 (UTC)
