monsters with no chest

HI,

In my third town i have 6 groups of yeti guarding a winding path that leads to nothing.

I also have several groups of big dendrogs but they guard a silver chest.

in second town my several groups of royal worms guard a chest and in main town the huge groups of muscards also guard a chest.

Are the yeti supposed to have a chest at the end or is it normal to just spawn mobs like that (and they are permanent type not the ones that reoccur at 24-48h intervals).

i used F3 on all maps, after discovering everything i could on the map the slow way (just to see how many monsters i would have to face and plan ahead) and the yeti groups were the only ones without a chest.

Ok, you never gave bad info so i will trust your input over the F3 data.
