If you have updated training requirements for a worker type, or if someone should have training requirements based on what you see but they don't, this may fix/update things.

1. Click "Training" on the top menu bar
2. Click "Worker Type / Training Curriculum"
3. Single click on the worker type you'd like to synchronize
4. At the top of the screen, click "Synchronize training curriculum", then select "Synchronize selected worker type only"
5. Click "Yes" when it asks if you are sure. It usually takes up to a minute.
