Anyone else finding the Quartz_Tan contracts keep crashing exactly 8 minutes into the contract?

Been an issue for me since he first uploaded his kill everyone contracts, especially on Miami, Paris and Sapienza. Always gets to the 8 minute mark and then I'm thrown to the dashboard and prompted to accept and report the issue.

It's a shame because I've done a few of them no problem, but I want to live out my BigMooney06 cosplay with Patient Zero-style "everyone's a target" contracts on all the maps.
