I also think that they stopped processing. Since I applied the processing time roughly increased each month by one month. And this visa is priority group 1. I am skilled IT person with research experience and my boss really needs me starting ASAP. My MA said it too risky for me to go on bridging visa, so I am on a student visa working part time.
I think they will change the rules retrospectively and that will cause most visas to be invalid. They take their time to define everything and so long everything is on hold.
BTW is there any other IT person waiting? I am in month 12.
