Another thing I noticed on the return trip:
TEI was nominal. VERY nominal as it turned out, all three MCCs on the way home were scrubbed and I hit right in the middle of the entry corridor!
Anyway, there was an issue when MCC tracking went to calculate my MCC-5. Obviously it would normally show "Thread Started" then "Thread Completed", then show "MCC-5 has been scrubbed". In my case, the sim hung after "Thread Completed" and I ended up having to restart Orbiter. It did it again 2 more times, and I ended up disabling MCC tracking and calculating MCC-5 myself with RTCC. The dVs were really small, I decided the maneuver was scrubbed, and once well past MCC-5 I reenabled MCC tracking after resetting the substate. The problem didn't reoccur for later MCCs, they showed the normal "MCC-# has been scrubbed" message and gave me the SV uplink. MCC worked nominally for the rest of the TEC and entry phase.
Here's the odd thing: It printed a nonsense MCC-5 pad in the MCCPreAdvisoryData.log file that never showed on the screen because the sim hung. Attached is a scenario just before MCC-5 and the nonsense PAD. Looks like maybe a divide by zero error or something.
