I figured out what happened. That was an old account I abandoned a year ago since I didn't create the keys securely. Sometime last week I attempted to connect my Mutiny wallet to Habla through NWC. I accidentally grabbed the old keys from an old Habla set up on a laptop, and used that for the NWC, which seemed to change my Mutiny default account without me noticing! Crazy. I lost the ability to zap as a result, but didn't realize the cause. I know, TMI, but thanks for noticing, or I wouldn't have straightened it out for a while.
