I was having some trouble getting this roll change to work.

It seemed the final process was:

1. Update calendars
2. Roll adjust (it still reads next month rather than quarterly)
3. Update sampled contracts

The contracts were then properly rolled over.

In between 2 & 3 I restored adjusted and multiple parquets from backup, but I had thought corruption when interactive_update_roll_status was crashing - rather it was probably just been not sampling the new forward.
