I'm not sure what happened, I've been trying to check my logs but all I see is random symbols, in every single log except for the latest log and within a day it gets corrupted. And I'm pretty sure this is just my one server. A tiny portion of one of my logs is "���ة�����f��zzj��捶" [�>!�諈Þk�$�B��]sÈJ��8=��b�K:KL��&>dP���� ��aݎ�" its just a huge paragraph of symbols and those question marks and it honestly freaks me out because I don't even know why it did that it's just been like that since I started my SMP. Is there a fix for it?
