KitKat/Lolipop rom with fully working GPS? topic

Hello. up until about 6 months ago I kept my nexus fully stock. I decided to try kitkat and installed LiquidSmooth. very nice room but quite buggy. GPS was broken and never really worked. went back to stock to check for a software issue but it worked perfectly. right now I've using CM 12 (beta) and it works quite nicely but again, GPS is broken.
My question is, is there any other rom with perfectly working GPS? or should I just go back to JellyBean?
thanks!
