This tx did cause us some issues. https://coinbase.com/network/transactions/88eb395b48a6d3875d8d55a6efd34afd2e1d4e397b43f9f790479914fba0c74b and should not have been used as an input - that was our error.
We are pushing out a fix for this now so transactions like this should not be used in the future. Luke-Jr was kind enough to starting mining it for us (we sent him a bounty). Hopefully it should be cleared up soon. Apologies again for the trouble and thank you for bearing with us.
