Sorry for another message, but I noticed other weird things. When your plugin is ON, the game starts as usual, but the player with his followers start to blink/flash until I move the player away for at least 2 or 3 tiles. Then they don't blink anymore, but they start again to blink if an item drops on to the same tile where is the player or where are the followers.
I also encountered another crash. After installing Yanfly Item Core and Yanfly Item Picture Image, the game crashes if I discard an item that has a picture image instead of an icon. Here's the console log:
