Hi there, i noticed on vanilla wow that my taxi nodes are disabled from time to time. I checked the flightmaster coords and they were okay, i deleted the TaxiNodes.xml so wrobot can make the file again from games data. But at the end i still saw some taxi nodes deactivated which were used before without any problems. I am not sure what causes these problems on vanilla. So i wrote a small plugin to activate all taxinodes every 5 minutes. I added my file. Maybe it helps
