Hey guys make sure in your survival trials you have 12/12 ninjas. Some of the missions will not work unless your roster is full, even if you complete what it says.

Example:


The mission "Pass the first 12 checkpoints in Survival Trail with a number of casualties equal or less than 1 during the event" did not get completed. I did try to fill my roster after beating all stages, before while doing the survival trial I had 10/12 ninjas.
