Wolfenstein Saving Problems

Some people have problems with Wolfenstein because it stops saving on the XBox 360 version. The problem is it is an autosave, apparently, and if it won't save, you need to go into the XBox 360 settings and set it to a later date, and it should save again. Why this helps is unknown. But it works.
