Hello there, sorry for my poor english ^_^

What I did :
I crafted a ForceField Controller to make a ForceField. I Right-clicked on 2 opposites corners of an empty area to make him. It works.
I wanted to remove it. I shift+rightclicked on the ForceField by handing the ForceField Controller to break it.

What it was supposed to do :
Remove the Forcefield

What it do :
The Controller selected the bloc next to the ForceField to started the creation of a new ForceField. It doesn't break the first one.

Edit Uuh, maybe it's a forge version problem, I run on 1.12.2-14.23.1.2573... If someone can confirm.

Edit Updating forge solved the problem. I feel stupid. Cya !
