Cause

nimbus interprets chainid 0x2939ab535c74e9aa824a2efbbc11f91c00000000000000000000000000000000 as 0, it seems to cap it to u64. This is erroneous behaviour and a prague-consensus error (or possibly a false positive due tot the parsing of statetest json)

[jangko]

We are well aware of this ChainId issue, see #2942
And will fix it.
