Yep, Enemy 106's companion was counted, along with an extra entry for the Visonyte I made for testing and then forgot about. I'll have them both fixed next patch. (Which will probably be tomorrow- I won't have much time tonight.)
Some of the sheeps' movements are randomized, but they're all generally confined to a single part of the map. On that note, there shouldn't be gaps there- but I do see one of the gaps. I'll scour the place for gaps and they'll be patched as well.
EDIT: I'm going to go ahead and make a proper entry for said companion, as well as another monster you "fight". These will be added by the Bestiary (and the junk data will be removed), so it'll cap out at 260 in this version.
