We have dedicated sub-forums within our Steam community where you are able to create your reports. This will allow us to monitor and update them seamlessly.
For more information about a specific bug report, you can continue to check these pages for updates.
If you find that this bug has previously been reported, we encourage you to file additional information on the existing reports. We continuously monitor all reports we receive but may not reply individually to each report.
You can also submit a support ticket to the help-desk. Simply select "Bug Report" from the form.
