ANSWERED MYSELF! => Tried a third time in a different difficulty and it finally worked. Got the achievement back and triggered Child of Odin. Hope this can help someone else.

i have same issue, then what exact difficult to achive that ? can you explain it clearly ?

i do this about 45 days survive and still max count 6

So what, changing difficulty will fix? i also encountered that bug. Do i need to do the 30 days again from scratch too? (also cant get Child of Odin due to that)

I got similar issue with Max Comfort by the way, did it a month or so ago, now it revoked and its stuck on max 2

I played previously in easy and hard modes, then tried waiting 30 days on normal (which I never played on the character). It triggered the two achievements immediatly after that. Just choose a difficulty you never played on. You can check your character statistics (days survived without dying) in the crow option.

Choose a difficulty you never played on your character then wait 30 days. You can check your character statistics for each difficulty in the crow tab option to make sure how many days you survived.

Well i will try that and hope it fixes...got the same bug for max comfort by the way, where the "max comfort" is stuck at Max 2 :D

Hope it fixes both, luckily u dont need comfort for other achievs and i got it unlocked on steam

Nah ok thanks i got the answer now. what you need to do is, you should typing /die to make sure it will count from day 1.
Then making new seeds, then build some small house just for sleeping. and use timer around 12-13 minute, for better strat im using max comfort of 5 . its around 12 minute, when time up. so you can sleep again.
"Survive for 30 consecutive days" IT MEANS, YOU SHOULD PLAY THIS GAME UNTIL DAY 30. DONT QUIT GAME OR IT WILL REPEAT AGAIN.
So basically, 12 minute x 30 days. around 6 Hours. Hope it helping

6 Hours later i can confirm, Both Survivalist and Comfort King did unlock (again) on new difficulty
