Can't sync when update testnet fxcored

Hello @everyone

i get error message such as the following
Error: error during handshake: error on replay: wrong Block.Header.AppHash. Expected 33BB8578B19087F7A57FAD7DC19B10630C24B25D532389DEBF42E296AFC7818D, got A90966236C1BFC19D62D5A2ACAAFDDAAB4C92D1762552BA63AC923676FD70B15

should i re-download snapshot or can fxcore reindex ?

Thank you

Sorry. Never had that. Try asking @Richard
