Extreme survivor bug- No Mans Sky (PS4)
For some reason, Extremely hot Planets are not counting towards the milestone for Extreme Survival. Also, if you feed the local wildlife- they'll bring you gifts.
UPDATE: The Achievement is for uninterrupted time spent on a planet, the counter resets every time you leave the surface of the planet. IT IS NOT CUMULATIVE. So if your experiencing this problem- You'll just have to wait beyond the amount before you start seeing progress again.
