Well, I found a huge number of bugs in group 1 over the years, and many of them were fixed in time before group 2 deployments. Now looks like there is no chance to find such bugs 5 hours or 22 hours after group 1 deployment and fix them before group 2 deployment. So, 97% of bugs will come to all wikis from now, instead of a couple of wikis. Hopefully it will not damage the normal work.
