The Hidden Forest

I tried to zone from the forest TL to Lower GuK and it sent me to log in screen, now whenever i get to the character screen it logs me out to the log in screen. Dunno if its zoning or something else thats my problem

Try the stuck character mover.

webtools/char_mover.php

This will move you back to the forest and try again. If you still have the same problem you could be missing or have some corrupt files.
Did you play on another server before coming to THF? Other server installs do not play nice with THF custom files.
