So they have in game confirmation they don't want to fight. Perhaps that has something to do with them being already hostile elsewhere? And despite that emeriti refused to accept an open c.f. offer sent by 4 19 while 4 19 was clearly hostile with 2 1? I don't know about you but if I hit into an active hostile I'll be first to admit mistake and offer reparations asap and stop damage, rather than leaving the c.f. unaccepted there and continue hitting.
