Yamato Alternate Fire becomes able to Critically Hit enemies when it is in Express Shot

[Acurrz]

This issue arose similarly to the Ricochet Yamato bug where Ricochet allowed Yamato Alternate Fire to Critical Hit enemies.
Steps to recreate:
Purchase Express Shot
Summon Target Dummy
Alternate Fire with Yamato
If aiming at head, both bombs count as Critical Hits.
