It mentions that a group can only find "one rumor at a location for each actively investigating PC each phase", but later mentions that for "every two PCs that investigate a particular location in one phase, reduce their final number of successes by 1 for that phase". My main question is how to handle it if a single person gets enough successes to get more than one rumor? This is especially challenging for when they get one or more true rumors AND one or more false rumors. Examples include: Single PC gets 1 or more sucesses. Two PCs get 1 success (does it drop to 0?). Two PCs get 4 successes at the General Store. Four PCs get 4 successes at the General Store.
I tried to use the best examples, but hopefully you get the idea.
