Apparently handle creation in AresCentral has been broken for some time. It should be fixed now. Thanks to Coin for passing the info along.
Game runners, please encourage your players to let me know if there are problems with AresCentral. I’m not in there every day, so if something breaks suddenly it might be some time before I notice if nobody tells me
On a case by case basis. It requires manual effort on both my part (fiddling it in the database) and your part (re-linking your existing characters), so it’s a bit of a pain. You can PM me for consideration.
