In the case of bugs like T116586, we've cached the old wiki name, and will continue to do so for a certain amount of time (in this case, 5 days)
We should add a sort of "Advanced" menu to allow users to force clear the ObjectCache in cases like this, rather than them having to find the ObjectCache.xml file in their user profile folder
This task has been assigned to the same task owner for more than two years. Resetting task assignee due to inactivity, to decrease task cookie-licking and to get a slightly more realistic overview of plans. Please feel free to assign this task to yourself again if you still realistically work or plan to work on this task - it would be welcome!

(For the records, two emails were sent to assignee addresses before resetting assignees. See T228575 for more info and for potential feedback. Thanks!)
