I've been trying to repair my diamond chestplate at /warp shop but nothing seens to be working. Am I doing something wrong?

 

Did you try right and left clicking it?

 

They have. I messaged them in-game about it. It doesn't seem to work at all.

 

Try moving around a bit; there's a bunch of floating words around it, which makes a "forcefield" around.

 

Gonna archive this, if you still require assistance please feel to PM a mod in-game or make a new thread!
