Sometimes, a mission might not load successfully from the database if the mission code file was corrupted or an outdated version.
In the case that a mission does not load after 2-3 minutes, delete the old code file and load the mission again.
Note: Your progress/score will be reset, and you will have to complete the mission again.
Steps to delete a mission code file:
1. Click on projects folder icon
2. Choose missions tab
3. Click the checkbox of the relevant mission
4. Click on Trash button
5. Reopen the mission.
