The more accurate subforum to ask this question in would be the Server Tournaments subforum. The other Tournaments subforum that this thread was originally posted in is specifically for forum-hosted tournaments. I have moved this thread to the Server Tournaments subforum as a result. To answer the question: I believe tournament information is reset at the start of every month.
WHO THE HELL DELETED MY 2000+ TOUR POINTS As stated above it gets reseted every year+ it's better in some cases to not lag if you try tourinfo some people who had wins from years ago
