Been having this problem post update 1.0.3 it seems. It seems to only happen with my Himalayan Brown Bears and my Formosan Black Bears, both are in exhibits with 6+ meter concrete walls on guest path sides and only viewing areas are 1 way glass, correctly placed. I won't have a problem for several in game years and then out of nowhere I'll get an alert that one or more of my bears are critically stressed and trying to hide despite there being no way they can sense guests watching them and both exhibits have ample shelter. Typically they will be at 100% in the green for stress and then quite randomly that'll tank to 0 and their welfare will go along with it. At first I thought there was some point in the fencing vs elevated path that allowed guests to see them, but I've rebuilt both exhibits and its definitely not possible. My Himalayan Brown Bears have some high mountain like elevation, but the Formosans Black Bears are in a dropped elevation exhibit where the guest path is raised slightly but the exhibit fence is 7+ meters. Himalayan Brown Bears make the least amount of sense as they are neutral towards humans and shouldn't have a stress drop like that anyway, but especially not in an exhibit of concrete and 1 way glass. I have snow leopards and red pandas in this zoo ( shy with humans) and giant pandas (neutral) all three in near identical exhibits and haven't had stress drops once in 52 in game years for any of them. Anybody else having this problem? Bug or am I missing something?
