I can't see anything obviously wrong with your task, but search your zone logs for the word TASK to see if there are any error messages when loading them.
Also you could add the line:
to the log.ini file in the same directory as your executable files are located (create the file if it doesn't exist), and restart your server.
This should write detailed information to your zone logs as the tasks are loaded from the database. You should see task 225 being loaded, or an error indicating why it is not.
