Villager randomly drops me books

Thank you for your report!
However, this issue is Invalid.

Your game, launcher, or server is modified. If you can reproduce the issue in a vanilla environment, you are welcome to create a new ticket.

• Any nonstandard client/server/launcher build needs to be taken up with the appropriate team, not Mojang.

• A world which had previously been opened with a modified client might be corrupted. Please try reproducing the issue in a newly generated world.

• Any plugin issues need to be reported to the creator of the plugin or resource pack.

• If you have problems on large servers such as Hypixel, please contact them first as they use modified server software.
