http://forums.ulyssesmod.net/index.php/topic,3847.0.htmlIf you're using release version, see if you have more detail to add to that discussion (though, we're no longer focusing on release much anymore..the only real reason we might do an update for it is if an exploit is found and we're notified)
If you're already using latest SVN versions of both ULib and ULX, which have been heavily re-written, and are experiencing the issue, please provide as much details/errors/time notices, theories, as you can starting a new thread in the SVN section. I suggest using title "<X> breaks after time"
