This occurs for three server resets in a row.
Basically one of pond npcs is always laying dead.

Each time it happens I can't actually catch the moment to witness what's killing her, but I have a feeling that this situation is somehow connected to what was said in these two bug reports: https://www.efupw.com/forums/index.php?topic=699001.0 (https://www.efupw.com/forums/index.php?topic=699001.0) and https://www.efupw.com/forums/index.php?topic=698969.0 (https://www.efupw.com/forums/index.php?topic=698969.0)
Why? Because the other two began to act strangely approximately at the same time when pondfolk npc began to die by unknown cause.
I have seen her alive. She is just wandering around at night, which I assumed is intended as a cautionary tale. Her inevitable death is a constant reminder that the Knaves, Peers and Blackjacks have an orderly queue of who gets to purge the Ponds' pinatas next!
