Hey there, I also have a problem with my logs. I could locate all the ones from the previous versions but since 0.4.01 has been released I can't find any "logs" folder though I checked I had selected the "log chat messages" option ingame. I don't know if it's because of the release or not.
If this might help I'm on a Mac. I didn't post this on the Mac-dedicated board because i wasn't sure it was a Mac-only issue, plus there was already an existing thread (an old one though).
If anyone has an idea about his, or has the same problem, please tell me.
