Describe your problem, including steps to reproduce it

Got a rather unexpected crash while doing some testing with the Spawner Extractor.

Steps I took to leading up to this:

1. Place down default spawner
2. Place down a vacuum pump and connected that to my air source
3. Place down the spawner extractor atop the vanilla spawner such that it immediately connects to the pump.

It crashed immediately upon placing the extractor.

Any other comments?

Layout was similar to this.

I've tried reproducing the issue in a single player world of the same pack and am unable to. This occurred on a server. It's the first time I've tried using it on a server and, unfortunately they have not yet been able to get it running again (admin is offline) so I don't know if I can reproduce it again there.

Damn, looks like I used a client only method there. I'll get a fix out soon...

Build 71 should fix the problem. I'll get a 2.6.1 release out tomorrow...

Fixed in 2.6.1 release (confirmed working on dedicated server)
