Interesting, please can you try with --no-warp and see if it fixes it?

Also, please ensure you're not using config.json anymore, with 1.6+ you can use --chain kovan

[yuanfeiz]

Yes, I used --chain kovan. Oddly I can't reproduce it for the moment, closing for now, will update once it happens again.

[IstoraMandiri]

Thanks, it was because one of the validators was on an older version; they've updated now so it shouldn't occur anymore.

It makes sense, thank you for the follow up!
