Why haven't they patched all the bugs yet???

You would think a patch would be out by now! The game is so glitchy!! Everyone has identified most of the bugs and glitches, why haven't they released a patch yet! I am at the point where I don't even want to play anymore because when I go to do a solo challenge there is a chance I get stuck on "waiting for players" and I have to restart the game (which takes a minute to load into a lobby). I can't progress any further in the story because I'm still stuck on Stunting 101 Step 3/3 even though it says I have completed it! It has grown more and more frustrating to try and play! I want to play but it's so buggy that I am no longer having fun! They need to release a patch and start working on fixing all these bugs!
