If your warband version has been updated to 1.150 or 1.151 a bug with the character creation system is causing the game to get stuck at banner selection. All of the banners will appear greyed out and nothing on the screen works so you're stuck there.
From testing if you load a 2.52 save game and then try to make a new character only the native banners are greyed out. If you try to make a new character right after starting the game then they all are. You can make a new character if you select a non-noble option. Windyplains 22:06, April 19, 2012 (UTC)
If you load a 2.52 save game with a character that has a banner you can select one and the presentation works just fine. Could the fix to the banner ranges be related to this? Somehow the banners aren't being initialized? Windyplains 22:11, April 19, 2012 (UTC)
A workaround has been developed to resolve the issue in 2.53 until an engine side patch fixes the issue (assuming that ever happens). 18.104.22.168 07:42, May 2, 2012 (UTC)
