On our yesterday's gaming session we encountered a possible problem which we couldn't solve with reading the manual. One investigator entered the Chapel in Dunwich (i think it was scenario 2) and was overwhelmed by cultists. Literally! Our keeper moved four cultists into the space with the investigator so that there were five creatures in one space and evading was a really difficult task. Even though the chapel has five spaces (if i remember correctly) only one was occupied with this heap.
Have we overlooked something in the manual or isn't there a rule that explanes this matter?
Cheers,
