Start a game on casual difficulty (you can do this on higher difficulties). Choose random starting country, immidiately fund Investigate Outbreaks and Field Operatives. Only this. Only. Now wait for "Experts warn permafrost mining in (country_name) may release pathogenes" event:


Now more waiting for second - DrillZero announces expansion of permafrost mining to (country_name):


and third - DrillZero begins permafrost mining in (country_name):


event. Save the game. That's the end of preparation section.

Certainly easiest one - you just wait for pop-up to appear. You can get Authority and response evolutions but nothing else. After a while, this will appear:
with your achievement.

Load preparation save. Send Field Operatives to DrillZero country. Now (suprise) wait. When you get "DrillZero Site Closed", immidiately save the game.
It will be useful in Ice Find achievement as well. Now evolve Authority 1 and Censorship. Again, wait. If you get "(country_name) thwarts censorship" (most of cases), get Fake News. And wait. If Fake News fails, reload. For all the time lost game will award you with:
And your achievement of course.

Load save from Snow Way, and instead of taking Authority and Censorship, get Vaccine Research, Government Partnerships and Outbreak Intelligence Unit. Now (again, suprise) wait, until game rewards you with:
and Ice Find achievement.

Well, you have enough patience to get those 3 previously bugged achievements. If you have any questions, correctons (I'm kinda bad at english) or other informations, write a comment below or ping me (same name) on Plague Inc discord server. Hopefully you're now one step closer to get 100%.
