Puting something inside a crusher that has no recipe minecraft crashes it dont matter if through pipes or the GUI

The same happens on 1.8.9-2.4.4.

Server crashes immidiately after joining.
Logs got deleted while restoring the backup, though.

Reloading the json files should help solve this issue, clean install works with no issues on server and client
