funny sim. but i survived 250 days with lucky high-luck roll , and there's no way to stop the game to get the 150 day medal!
EDIT:finally died at 313 days, suddenly lost 70+ health from fighting gibbons or something.
150(etc) day achievement is shown in-game but not on NG's medals. meh. buggy medals again.
got another 200-days game and got the 150-days medal. it seems that i can't get the 150-days medal UNLESS i get the lower-days medals first?
