No entropyCallback on Sanko Testchain - sequenceNumber 433

Hi Dev Support,

we tried many calls to our smart contract but none of them received the callback. See for example transaction 0x5a246311496ec133ce80a20192ba7438971e6c6c4ba13f09351985b82e72fedb

Our callback implementation is super simple:

function entropyCallback(
uint64 sequenceNumber,
address provider,
bytes32 randomNumber
) internal override {
emit RandomNumberResult(sequenceNumber, uint256(randomNumber));
}

Thanks for your assistance.
