For some reason the checker for GC7T5BA is returning an "Unknown error". The script name is "Generic Oldest in N Regions (by sloth96)". I ran the checker for GC7MN04 which uses the same script and it gets the same error. The script was last updated on 2019-12-26 and I'm sure I've run it since then, so it doesn't seem likely that a bug was introduced. Any theories as to why this generic error is being returned?
Are you able to run other checkers? I've successfully run the checker for GC7T5BA for both your username and mine. Or were you trying to check another user's qualifications? If so, please let us know which user.
I was able to run all other checkers I tried, but that one script failed. I was checking for my user and for other users with the same behavior. However, this morning it is working. I guess I'll just have to live with the mystery. Thank you for your reply.
