Thanks for the answer, I just wish that the instructions for order in which to pick fleas were as clear as you had stated, but unfortunately that is not how I understand the rules as in the S-car
“It is also possible to divide a swarm of fleas by choosing to move one of them.”
this statement is written without regard to there being any fleas in the supply or available as latent.
also
“The region affected is now an ‘inactive’ Plague region. All adjacent flea tokens
should be turned onto their ‘latent' sides; from this point on, fleas tokens must
be moved out of an latent epidemic region, rather than the supply.”
states that latent fleas should be used before any remaining fleas in the supply.
again thanks for the prompt response
