screenshot shows the adventuring page i am currently on. the cream cat is the one who is moving, and she is able to move to the square indicated without a skill check, which as far as i know shouldn't be possible. i have seen situations very similar to this on the streams map with the river on the right-hand side when enemies spawn in a certain position

I've definitely seen similar things happening with sneak. I've assumed it is in some way related to the fact that you can always move into the the first square that requires a climb/jump/swim check (based on the automated pathing system). It doesn't appear to be consistent with sneak though. I'll try to watch for it happening again and see if I can get some screen shots to add.

example of what i mean by that one particular river spawn:

the cat moving has a movement range of 7 and the circled square would take 8 to get to, thus is an example of this bug
