Today's Kill Team reveal solves at least two Rumour Engines: Solving: 19 July: And 26 July: Grrr, !mrahil
One possible solution I am not quite certain of: For: 13 December: On the hip of the guy in front Grrr, !mrahil
Thanks to @NIGHTBRINGER (which is not good for his humility) I saw the solution of a Rumour Engine from 2022 in last weekends reveals: This unfortunate soul solves the rumour engine from November 1st: Grrr, !mrahil
