Let's take this one step at a time.When you set up your CIT account, you did that here, right?
You should be able to use the same page to change the global ID associated with your Titan account.
When you view the character info in Sentinel, does it display the correct global ID for the character?
Where are you viewing the character on CIT that it appears to have the wrong global?
What global do you have listed under "Privacy Settings" on the CIT Account Settings page?
(The global listed under "General Information" on that page that can't be edited should match whatever you have entered in your Titan account information. The one under "Privacy Settings" is the one you'll see next to your character names in the Leaderboards section.)
Recreating manually, or with Sentinel?
Do you happen to have the exact text of the message you're getting?
Are you viewing the Full List or Text List? Where are you seeing the wrong global ID on the "My Characters" page?
Sorry for the slow response, it took me a while to get back here.
The problem with the global seemed to resolve itself. I was having trouble with the first character from my second account, but I finally deleted the one that came in from Titan Sentinal, recreated him manually with the right global, and now it's mostly working correctly. Other characters from that same account are coming in from Titan Sentinal with the correct global.
In answer to your questions, I put used "global 1" when I set up my key, and now have "global 2" under 'privacy settings'. "global 1" was showing up on the "edit character" page for my "global 2" character, but now it is displaying properly.
The only remaining problem I'm having is that for 3 of the 4 "global 2" characters I have listed in CIT, it's not picking up all the badges that have been awarded. For some reason, vet badges only show up consistently on all of the characters. I have tried editing badges, manually adding badges, etc. with Titan Sentinel up when the character has logged on, but so far, no good. It is reading the badges correctly for one my second account characters, so it could be something quite different than a two-global problem. (The correct global does show up in Sentinel, btw.)
Any suggestions would be appreciated!
