Correctness of test vectors

I'm trying to implement ProgPow 0.9.4 in Scala from the spec described here, but I have a problem matching test vectors from the repo to my results.

The problem starts in obtaining hash_init so I will focus only on this code:

  case class Hash32 (uint32s: Array[Long])

  def keccak_f800_progpow(
    st:   Array[Long]
   ): Hash32 = {
    for(r <- 0 until 22){ ProgPow.keccak_f800_round(st, r) }
    Hash32(st.take(8))
  }

  def keccak_f800_initial_pass(
    header: Hash32,
    nonce:   Array[Long],
  ): Hash32 = {

    val st = Array.fill[Long](25)(0L)

    for(i <- 0 until 8) { st(i) = header.uint32s(i) }
    st(8) = nonce(0)
    st(9) = nonce(1)
    st(10) = keccakf_rndc(0)
    st(18) = keccakf_rndc(6)

    keccak_f800_progpow(st)
  }

  def hash(
    prog_seed:  Array[Long],
    nonce:      Array[Long],
    header:     Hash32
  ): PoW = {

    val hash_init = ProgPow.keccak_f800_initial_pass(header, nonce)

    // Further code is irrelevant as long as hash_init is wrong
  }

The code is pretty straightforward and I don't see where the mistake could occur. The previous version returns values as expected (passes all vectors from repo). ProgPow.keccak_f800_round passes test vector (I am not sure why this vector is removed from your repo) and nothing changed here from the previous version.

My results of calling hash function are:

hash_final: 2ae94b9ded0f6bac6cdb4348a6481c3ca07899aef390585a19a38a554ac25228

Could you please tell me if there is sth missing in my implementation (or maybe I misunderstood something)?
