A trick around the bug for the games is to quote the post in question to see the edited text. As far as I have noticed, on quoting, you see the latest edit. Just inform everyone participating about it. Better yet, tell all managers to mention this in the first version of the post that they expect to keep editing.
Yes, I did it at the top of the messages where I am constantly editing, but some players don't read it and directly go to the real content of the message and they find strange to see a very old version. Managers of PAW and other games should tell the users that they should quote the message to see the latest version. The fact that when editing or quoting a message with that bug then you see the latest version means that all this problem is an issue of how the post is shown to the users.
Maybe and Admin should delete the cache of the forum (if this means that nothing will be erased) to see what happens.
