Everybody on my servers are happy with the half height walls, so I'm good. ;-)

The barrels look much better as pipes. Did this get added?

Not yet. Some of the updates to Rust have been causing some issues with the core code. I'm in the process of re-factoring the code to make it more maintainable. Part of this will be to adjust to using Barrels for pipes.

any way you can add auto turn off for furnaces?

That is also on the list. 

cool thank you. cant wait for update now :d
