Have you ever wanted to instantly crash any server?
Just place down a belt of any length, and put an extractor facing upwards at the end of it.
Then all you have to do is to throw an item on the belt, and there you go! Server's done for!

In the future, please provide crash logs for a crash issue report.
Considering extractors have been removed for quite a while, i will move ahead and close this issue, it doesn't seem to be relevant anymore.
