Problems: 

There was an Hexapod failure at 22:28 local time. The problem happened right after large slew of the telescope, and it was fixed by Claudio and Rodrigo in a few minutes. However, the (next) exposure was not restarted automatically by the system and I had to reload it to the queue.

Decals machine error at 4:31 local time. It had to be restarted.
