The RFTools Elevator Screen Modules log every click on each button to the console.
While I assume this was useful for debugging before, it's been working quite stable for me for months so I doubt it's needed anymore.
Not an important issue or anything, just a minor annoyance now that players on my server have found out they can use it to annoy me...

Thank you for taking the time to create this issue, as we're no longer supporting versions below 1.12, I'm going to go ahead and close it but if this bug seems to continue over to newer versions, please do report it again so we can investigate the issue further.
