Hydrocraft (Build 40)
How to get items with no recipe or spawn location?
This is probbably the first time iv actually posted something like this because google provided no answers at all, so for obvious reasons don't suggest serching google..

I am new to hydrocraft and for over an hour now I have been trying to figgure out how to make the log barrier?

Looking at the hydrocraft wiki (http://www.aggressivegaming.org/newdawn/wiki/ they say this list is complete when it is clearly not?) and there is no recipe listed to make it and it also says there is no spawn locations found for log barrier.

Looking at the crafting menu in game i can't find it anywhere.

Its the same with the stone pillar also.. how is everyone building things that have no recipe listed and no listing in crafting in-game?

I'm tottaly lost, would appriciate some help
