[Bug] Dual Talent Client Crash

On each of my characters that I've gone to purchase Dual Talent on, the client crashes as soon as I purchase the ability.

This has happened with 3 separate characters. Confirming the option to train the dual talent crashes me out back to the log in screen. I can log back in and will have access to the new tree.

Switching back and forth doesn't seem to cause an issue. Just the initial unlocking of the second tree.
