Please put only one bug report in each ticket. It is very difficult to keep track of bugs when they are not in their own tickets.
However, please review the Bug Tracker Guidelines before creating new reports. Be sure to search for an existing issue as it is likely to have already been reported.

Please make sure you provide accurate information for tickets. You cannot play in realms with the beta version, so make sure you pick the exact version you are using in future reports.
