Feral Heart

So, everytime I get onto feralheart, there is probably a 99 percent chance that my game with shut off, i have asked others about this and they told me that it was because there is 'bugs' in the system. It has been happening for a while and I can't go anywhere else besides Lonely Cave and then the snow place (forgot what its called at the moment) I own a Mac computer, can someone pleas help me? And I just got mass markings to work for me now it wont let me play, advise please?
