It seems that topics get auto closed if they don't have any new comments for a while.
Although I understand that the purpose of this is to prevent spamming, those of us working on custom scenarios need to be able to update our topics, even after a period of inactivity.
By starting a new topic, all previous discussions get left behind in the old thread, making it harder to find chronological information about the map's development and changes.

Please consider re-opening the threads in the Scenario Design subforum or just disabling auto closure to allow continuous improvement and discussion of custom scenarios.

Thank you for your attention to this matter.
