大家幫我看看我的485怎麽了？

以前查我的485 CASE STATUS， 還都顯示在處理中，可是10月30日我發現的CASE被Update了。可內容如下：The status for this Receipt Number cannot be found at this time in this automated system. Please check your case receipt number to see if it is correct. If you have questions or concerns about your case status, please contact the National Customer Service Center.這是怎麽回事呢？我的Case就這麽丟了嗎？
