minecraft 1.12.2

I went to the the builder he was standing at his hut like he needed something. I right clicked on him and then clicked on "request". It showed "sprice fence" required. The clipboard didn't show this.
Then I clicked on the button to show details on the "spruce fence" to see if it was coming from the warehouse.

Crashed when I clicked that.
The clipboard only showed "rack" as a request.

Ok thanks. That did it for me. I got everyone working again. Guard/miners/lumberjack/fisherman all working again. D-Man are working delivering stuff. Great job....... Dedication is amazing. Everyday you guys get something out the door even though it is Alpha version and we all know that means buggy.
