It looks like the superblock did not emit for block 161560, most likely because of the switch to and back from DM mode.

I will investigate this.  In the mean time, I enabled deterministic mode for all sancs, so please upgrade your sanctuary to deterministic if you have not yet.
(As I dont want to take any chances with the next superblock).

Most likely the problem was that all the votes were erased for the GSC contract for this height, but they were displaying on the screen as if everything was fine, but behind the scenes they might have been invalid.

We will need to watch this next daily superblock closely and see how the sigs are formed and that they are honored in DM mode.
