When you come across extra invite only GAs like that, you can get some more info by looking at the dates when the GAs were created and end. The GAs in this train were created 4 hours ago (from the time of writing this comment) and end tomorrow. The extra 5 GAs were created 2 days earlier, have a lot more entries, and end Nov 12th. That indicates to me that they are most likely from a different event and there is no extra puzzle here.

no other jigidis, just the one. the other invite onlys are for Icaio's memorial
