Greetings, Feral Savage! We would like to inform you that closing a ticket does not in any way impact the outcome, or investigation of a report. When tickets are placed as 'Closed,' it is so our team is able to see who still requires assistance, and helps to prevent the flooding of unwanted messages being sent out.
I do hope this answers your question, and feel free to contact us through the in-game support desk if you have any further inquiries. We will be happy to assist!
