I just got done confirming the v1.3 patch has an online kick bug!!!! GRRRR
Go to this thread where we are talking about this bug:
Help! I cannot get into a ranked match Ok I'm back from testing kick bug and I can confirm if you do a GRID World offline tournament and then go online, you will be kick from any host you join!!!!

I tried joining about 5 different hosts online and every time after I got to the lobby, I was kick from host. And going back to main menu and then back online did not help, still got kick from host.
So then I restarted GRID like Loggyloggy said to and I tried joining a host I had not try before and was able to join and not get kick. Then I tried the hosts I got kick from earlier and I got a banned message from all of them.

Now I will have to wait for host to change before I can join ( maybe ) or wait for some new hosts to go up.
Codies, why would racing offline get you kick online??
Now I will have to go spread the word online to watch out for this bug this weekend. GRRR
