so i only started playing a few days ago & just got my 1st polar bear. my zoo is in a temperate biome & though i added coolers to my polar bear's habitat, i'm still having an alert pop up about 'animal is not in ideal temperature' every single time he gets in the water. i tried with & without the water temperature regulator & the water is still always too warm for him. is there any way to fix this, or will i just have to eternally deal with that alert popping up every time he goes for a swim?
