This is a known problem. But I'm not sure if it is really a problem with the ROM. Meanwhile I don't think so.

Another problem is the GPS. It worked just fine with the ROM from03OCT2012. The later ROMs need 5 minutes and more to get a stable GPS signal, which makes it impossible to navigate in time. As it worked I'm asking myself what happend with the GPS?
I helped myself with a fresh install of the ROM and the gapps. So make a backup an try if it works this way for you.
I have this problem every time a make a ROM update, because I don't like a fresh install, losing all my settings. Even make sure that there is a GPS source selected within the system settings.
In my opinion some GPS apps don't get current AGPS-Data. In this case I use the app "GPS Status".
