Do the sanity loss cap rules apply to seeing corpses?
The rules for sanity loss state that once an investigator have suffered the maximum sanity loss for seeing a mythos creature, any further loss is negated. For instance, if they see a ghoul (sanity loss 1/1d6) and lose 4 points, any more ghouls encountered can only result in 2 more points of sanity loss. Once that max loss is reached, the investigator will suffer no more loss from seeing ghouls.
So, does the same cap apply for other sanity loss sources? If they see one dead body and take the max loss of 3 points, then later come upon a dump-truck full of corpses will they suffer more sanity loss? Or do they build up the same sanity loss resistance described for mythos creatures?
