Its not a bug report, its technical help 
Which file are monsters stored in?
I am wondering if there is a way to regenerate wandering hordes. Changing spawn rate would be a bonus.
Hm, it seems that they are stored in overmap file. Too bad, since i cannot copy it over from another world or anything… Well, i could but that would be very silly.
What are these entries about, btw:
