It broke in Season 6 and was fixed a few weeks in.
It broke again in Season 7, and there has been no sign that its been noticed by QA.
Problem: Setting any HUD setting to show on 'mouseover' (only, i.e. uncheck always and other settings). For example, other player -> name, results in it actually applying a setting of 'never'. I hope you can see how this would be an issue.
Any update on whether this is being investigated would be appreciated. I've sent in bug reports previously, which have either gone unread or misunderstood.
