UPDATE - New contract address

There is a new contract address for HAVs: https://blog.havven.io/havs-now-have-a-new-contract-address-c870d7db7ad8

Any token balance of less than 50 HAVs did not have their new token transfer appear on EtherScan. Once wallets with a balance of less than 50 HAVs send a HAV transfer (even of 0 value), their balance will appear correctly.
