This needs to be lifted into the last callback above. So instead of
```javascript
                loadComments(pull, function() {
                    nanobarIncrement(increment);
                    loadStatuses(pull, function() {
                        nanobarIncrement(increment);
                        loadCommits(pull, function() {
                            nanobarIncrement(increment);
                        });
                    });
                });
               loadMergeableStatus(pull);
```
you need to change this to
```javascript
                loadComments(pull, function() {
                    nanobarIncrement(increment);
                    loadStatuses(pull, function() {
                        nanobarIncrement(increment);
                        loadCommits(pull, function() {
                            nanobarIncrement(increment);
+                            loadMergeableStatus(pull, function() {
+                               nanobarIncrement(increment);
+                            });
                        });
                    });
                });
-               loadMergeableStatus(pull);
```
