Flying in outdated content, working on achievements.
Had the issue earlier. I just logged out, deleted the wtf file, and logged back in. Works fine now. Was only affecting my toon in Org. I could get to every other toon except that one, but deleting the wtf file resolved the issue.
The issue was previously affecting a couple of the different Battlegroups, however it should be resolved now, please let me know if you're still having this happen. The forum post about the issue can be found here:
