We have the Bitbucket-Hipchat integration add-on, and we have configured an association with a hipchat room for events from bitbucket. It is very useful and we use this for all our pull-request and commit events. But on a very random basis, there won't be any notification, and when we go to the config page, we see the association entry deleted. If we can see an audit log to see who/which process has changed this association?
