Virtuous mission images are wrong. For the south they are together at the top of the path straight across from he limb that the bag is on. For Dolinovodno, frog is on the left post of the bridge, duck is on the cliff to the right of the path to Rassvet. (kinda striaght ahead after getting off bridge and go around the mound.
Dremuchij South and Dolinovodno

could use a few edits to be more neat and streamlined, like adding a tab for when operation snake eater starts and the chase sequence but overall pretty good

If you add the ones during the chase it will be perfect

Dremuchij South in Virtuous Mission is from the second time (Operation Snake Eater). You used the map twice. Same for Dolinovodno.

Dremuchij South is wrong but okay.

I've just started playing on extreme and at least the ones on Dremuchij South aren't where they should be.

different locations for me (normal)

Mostly ga-ko and kerotan are not in correct position in based difficulty differences i was playing extreme diff and sort are correct and other are not correct as shown maps.

in dremuchij south they are right beside each other, though people are reporting that they are in different locations based on difficulty

Dremuchij South for me had both of them next to each other when you looked east on the branch with the backpack on it, on very hard. I think they change for the new game or difficulties
