Alright, here is my question for the day..... I am trying to figure out what exactly this is and does....ttnlog.txt.... I tried to google it but only find limited information on it. We have some players that have been kicked off servers and have been PB banned after it due to this file. Is is 100% sure that this file was created due to a cheat/hack? I don't want to kick someone out of the clan/club without being 100 % certain....any help is appreciated..... Thanks,
