If you really want to turn off Career Enders, you need to get to the injuries txt file and turn off the flag that makes a possible injury a career ending one.

I've never messed with it but it looks like the 4th number is the setting with a 0 = not possible to end a career and a 1 being possible to end a career.

The attached is from when I cracked open an older version, but I presume there is a similar file for OOTP 25.
