Hopper pipe / Daylight sensor

[DocSlyper]

hi there,

first time running MCServer on my brand new Rasperry Pi - and it's working fine

But when i try to rebuild some things I've build loooong time ago it's not working.
So the hopper pipe. It's not possible to build hoppers in a row/line. When i want to place a hopper next to an existing i'm operating this hopper .....

Same with the daylight sensor - can't switch it to a night sensor.

I'm doing something wrong?

MCServer: Build yesterday from Git
Client: 1.8.3

Thanks
