"Gyms that close at night not generating Raids"

#PokemonGO: It seems as though gyms that close at night do not get any raids, even when open during the day.In my town we have a park with ~20 stops and 2 gyms, and since the last round of added gyms and stops, they all close at 9pm, including the gyms. Everything reopens at around 6am the following morning, but the gyms have not had any raids since the closing started. I distinctly remember participating in an Articuno raid in the park prior to when they started closing at night, so they have had raids in the past, but not any more.Is this a bug, or is this intended? via /r/TheSilphRoad http://ift.tt/2eMqwdS
