Before, only one pairing was looked up per agent. Now every active pairing gets the activity.\n\nEach turn records which pairings were open when it started. A pairing that becomes active partway through a turn does not get that turn's opening activity.\n\n**Why**\n\nSeveral observers can follow the same agent, and one that joins late does not receive half of a turn.\n\n- Area: Subagents\n- Tier: You'll notice\n- Useful: 2\/5\n- Signal: 2\/5\n- Scope: individual\n- Heads-up: no"}
