It sounds as if the original receptacle was wired for two hots (black

Illegally? I don't think so. It's quite acceptable to feed single outlets on
a dual recepticle from multiple circuits - if done correctly.

Doesn't doing this require that both circuits be protected by the same
circuit breaker, i.e. a double-pole breaker? It soounds like the OP
had separate OCPDs on the two legs of the multiwire duplex receptacle.
