On Server B my character (Selds'fryn Torviir) and Blackjack's (Iym'iira Torviir) are being booted at attempting to log in.

We can log into Server A fine, but any attempt to go to Server B results in the following error, the same as if we just tried to join server B.

Error is:

Invalid Character - Player Login Refused.
Invalid Ability Scores.

Issue seems to be resolved!

I don't know why, but I'm going to thank the DMs anyway.
