Grimm's Hollow (Japanese) - Attack animation is incorrectly displayed on the Player

[Mimigris]

Name of the game:

Grimm's Hollow in Japanese (tested with the Steam version). This issue does not occur for the other languages (when playing in Portuguese there is another bug but this is an issue with the default game so unrelated).

Player platform:

Windows, 64 bits continuous build of the Player.

Describe the issue in detail and how to reproduce it:

During a fight, when using the normal attack in the Japanese version of Grimm's Hollow, a square is displayed when your character moves to do an animation in the Player, while this is not the case in the RPG_RT. This issue seems to appear only in the Japanese version of the game. The RPG_RT of the game was edited for this game but replacing it does not change the result at all so this is also unrelated.
The square present on the Player's screen is actually a Battle Weapon called NA. Since the image is not indexed, RPG_RT will just ignore it since it's a fight, while the Player displays it anyways. This issue is not present in the other versions since this file is not present at all.

With not indexed you mean that RPG_RT fails to load the file and just ignores it?

The behaviour in battle is in general weird because RPG_RT will ignore alot of issues.
