Good morning bros. On the topic of IS2, I spoke with some CN players and found out that clears completed with Castle Sightseeing (the lowest difficulty) don't count for relic or squad unlocks. In my experience, however, they may be bugged regardless, as some relics are still locked on my account despite having cleared on the higher difficulties. I'll make a note on the wiki about it but I'm surprised there's a limitation on those, not being able to access Tactical Assault Squad immediately (or any of the instant promotion squads) would make clears a lot more difficult for newcuties.
