Forestry Still -> Waterproof Pipe problem

[Serendipiteit]

Hey guys, using Buildcraft 3.5.0 and Forestry Beta 2.1.2.31 in 1.5.1 Server. Forge build is 675. Every time I try to pump biofuel out of still using wooden waterproof pipe, I'm getting this 'rendering tile entity' crash, and so does everyone around the area. Server itself is all right, just that any client that comes within the accursed still crashes. Is there any fix for this? I know you can use liquiduct, but liquiduct's an expensive thing to get when server started a minute ago.

Thanks!
