Sometimes, there are issues that affects one or many nightlies, and that are carried over since a stable release, or even before it.
For example, I'm currently running a CM13 nightly build, and have a Wi-Fi issue that's present since the first CM13 nightly, and which affected even the one stable build that was rolled out some months ago.
Given that the issue never changed, and so it doesn't depend on a specific nightly, which policy should be applied? Should such a question be flagged? Closed? Would it be legitimate to ask it?
