So far I've notice that constructing the sickles will cause a random crash.

and when building items like the craft table on a stick, it will auto deconstruct with removing extra material from the craft area or exit the menu.

Please fix (minecraft 1.11.2 forge server)

What the heck is a sickle?
Try this without any other mods installed. Also, without crash reports, I can't help you.

Closing this because of missing response.
