UPDATE FROM MABULA
I have had a very rough 2 months unfortunately health wise. I was struck 3x in a row with bacterial infections. The second infection occurred  after a routine hospital checkup and I became very sick. I had to rest and take a lot of antibiotics. Once I was recovering and restarting work 1 month ago, I again became sick. The infection was not yet gone, so even more antibiotics and rest was needed. Needless to say, it took a lot of my energy and I needed a lot of rest.
Finally, the infection is really gone and my energy is coming back step-by-step now and I have started work again. I am terribly sorry to have kept you waiting for support. I will address all outstanding questions and e-mails step-by step and will be on the forum daily from today.
APP 2.0.0-beta47 will come soon as well, a lot of work was already completed before I became very ill, so the release is also nearly ready for you. Beta47 will be much faster actually. Many workflows will be more than 2x faster, mosaics can even be 10x faster than before because registration really received a major boost... all compared to beta46. Â Before I release it, I will make sure that everything is working properly and then I will release it.
I've been stuck on saving 47 calibrated lights for an hour now. Anything suggestion to speed it along? My system has an i75820, 64gb ddr4, I use a 2tb Intel 660 ssd for light file storage, an intel 730ssd for my calibration library, and the application is running on an Intel 750ssd. I'm not used to things taking this much time.
The actual saving takes that long or the registering process? You can check what it is doing on the console.
It was the saving that took that long. Not sure what happened. I ended up killing it via task manager, then tried again on a different set and it did the same.
Ok that is weird indeed, on a Windows machine I see? Does it do the same when trying to save, say 11 frames?
I ended up clearing it by restarting my computer.
Ok, interesting, thanks for sharing the solution!
