Fleas should give the plague

I don't consider it an exploit. It's a tradeoff. Sick wolves need double the amusement as regular wolves. IF a player believes that to be worth disease risk than so be it. A real exploit would be if fleas barely affected your pack but still protected them from illness.

Im going to have to no support on this one, making rng an even bigger pain in the ass is just not good

HUGE support! I know wolvden isn't very realistic, but in real life when wolves have young pups (that still live in/around dens), getting fleas is one reason for them moving the pups to a different den site. It's something wild animals don't like and avoid, and implementing an accurate reason to keep players from abusing the illness system is a good idea. Even if there isn't a penalty for the adult wolves (besides the mood loss), there should be one for pups.

For me, the double consumption of amusement kills the flea strategy for me. I have a large pack (which will get only larger) and it's killin' me lol. I do support the idea of getting the bubonic plague on board tho. that sounds like a rad idea.
