A scroll seems to be malfunctioning. It has no description or name.
When I hover my mouse over it while the interface is open (for example, during a sale), the entire game interface disappears and the game becomes unresponsive.
I can click on it and examine it more closely when it's on the ground; at that point, it doesn't malfunction.
However, nothing happens when my colonists try to read it. They pick it up and immediately put it back.
The "details" tab tells me that this item belongs to the "books/scrolls" category. This item does indeed come from your mod. I don't have any mods that add or modify books, scrolls, or diagrams.
Sorry for my english (google trad)
