Hi, i noticed a problem with Isla Muerta. When i select the day/night cicle, altought the sun rises, it gives me the sensation that there is only dusk and night, not day. I don t know if this is my problem or a game bug .
It seemed to work fine for me. Although 1/3 of the park seems to always be in the shadow of the mountains; maybe that's what you're seeing. Try setting time to just fixed midday and compare or set the day/night interval longer.
