Wikimedia Bugzilla is closed!

If you save a page, realise immediately that you made a mistake, hit the back button in your browser, make the change and hit save again, it usually works. However, if you try it on a discussion page, where you've signed your name, you'll always get an edit conflict when trying to re-save. The diff that shows the changes between your version and the stored version, however, shows only MediaWiki's expansion of '~~~~' into your signature. Since you don't normally conflict with your own edits, I can only assume the conflict is with the signature expansion, I'm not sure, but either way it would be nice if this didn't happen.
