Changes
We've added new cards (4 unit types, 5 skill types).
We've deleted the [AI Book Lv2] from the training section.
We've added [AI guard book Lv2] to the training.
We've increased the battle rewards for Training book lv 2.
Fixed the following issues
There were instances where the [AI thief book Lv2] training became unplayable.
When [Mine Trap] was triggered on a unit with HP change immunity, its HP would decrease only on the screen.
In some cases, the total number of collected card types displayed in the album was one more than it should have been.
