I did not realize that the name change on Twitch would mess with the tokens

My twitch nickname was jman2907, it is now jman123. Apologies for the inconvenience, but could I please merge my tokens to the new account? Not sure if this is the right place.
(I tried to log out completely from the cohhilition website per Rodr1c's instructions on another user's name change, but even with all cached items removed it still seems to be saving login information. Not sure why on that one.)
Many thanks,
Jman123
