I found a bug with Tanegashima Tokitaki unit. In custom battle i use this unit as general unit. My soldiers dueled with another misssile unit. But they don't shoot, they just walked on the enemy while they were shooting. The soldiers died on the way. In the next time they came to the enemy and just stood there. When i used this unit as not general unit, the soldiers behaved as they should. This bug needs to be fixed.
