The HiTech team is hard at work finding causes to bugs, fixing them and then fixing bugs the changes cause. It is a process that takes time. I have seen companies release patches once a year. These guys are getting patches out at least once or twice a month with the new graphics engine. I expect that you will see a new patch in a week or two.
My hat is off to the technical team... they really have shown that they care about the user experience and retention of clients.
If you are having any particular problems with the game, we are all here to help as well!
