Clicking on boxes often does nothing. Have to click several times to untie the box.
Any chance you can improve this?

You need to hold the key down until it releases. That's how it is in vanilla. Not much can be done to improve without hurting server performance.

But I thought the purpose of this plugin was to let crates go up within one second?
Which sometimes works and sometimes not. That's what I wanted to mention.
I don't know if it's possible to improve this but I would appreciate it.
Thank you.
