This incorrect diamond display bug should be prevalently published on the Wiki page, along with all the other unfixed known bugs/ Players shouldn't have to spend hours poring through the thousands of Forum posts in order to glean important information that cam radically alter theikr game play. I understand that most Forum moderators, if not all, are players who volunteer their time to help us all, and probably don't have the power/authority to make changes/restitution in the game; that's the reason for support tickets. However, players encountering issues that remain unfixed are right in posting them as a warning to others - but it only is effective if the post(s) is/are read before the incident occurs. That's why I advocate that unfixed errors be identified and posted everywhere that players are likely to read; at least in the Wiki and Facebook sections.
