Through the use of a custom user field, and usergroup promotions, I've given my users the ability to change their username display color/banner color. Everything seems to be working fine except for one user. (if others are having the problem, they haven't said anything).
This user makes the selection in the custom user field. The cron job runs and the user promotion manager says that the promotion was made, but the user never gets put into the secondary usergroup that will give her the color that she chose.
Any ideas? I tested it with another account and it changed everytime the user was promoted into a different secondary group after the cron job ran.
