as of 1.58, is the 'reset when leave planet' still a thing?
on xbox, i had 6.3h of survival time, and then i went and did an extended errands run on an Extreme planet, and the next time i checked, i saw i had 6.9h of survival time.
i absolutely for certain was not doing things for 6.9h that last little bit. it seems like the "on planet time" is added to the total, and not "every time you enter atmosphere then touch down the timer starts at 0 and ends when you leave atmosphere". Jrrs (talk) 20:44, 4 September 2018 (UTC)
Current PC version[]
Not sure when it changed, but at least on the current PC version (orbital), hiding in exocraft, underground, in buildings etc. pauses the extreme hazard counter. Extreme weather on non-extreme planets increases the counter. Basically, I think the counter increases when the exosuit hazard protection is actually affected. Leaving a planet or a hazard environment does not reset the counter.
