In the Topic's feed, you still have a few features you can use to manage it effectively. You have the Moderation Log and the Queued Posts pages available, as a Moderator. Next to these, you will have a button to go to the Moderation Discussion and Moderation Requests.
Selecting Moderation Log will take you to a new page, exclusive to Moderators, where you can check what the other mods have been doing on the topic, as well as undo any one of their actions. You can Undo an action using the button found on the right side of each item on the list. This will also lift the Ban on a specific member if you undo that action.
