God help me, I laughed.
But yeah, I’ve had this problem before-- just not in the evac shelter. Mine was a fortified public works with no anthill in sight.
I don’t make a safehouse anywhere near an anthill now. If you go to sleep they’ll be clustered around your windows in the morning. Not sure how they can hear me or smell me when I’ve not moved or left my shelter though. Do not get surrounded. If you are unhurt you should be able to outrun them.
Don’t sleep within 10~15 or so map tiles of an anthill on the map or this situation will be guaranteed to reoccur.
Luckily, ants, soldier ants and ant larvae cannot break through windows or doors. haha, stupid bugs
