I know how to chop down trees and such, but when i place a blueprint one of the guys places 1 log but then nothing happens and i can't click on it or anything, and it acts as if it hasn't been built yet.

This only happens for stuff like a fishing rod, i place it on a raft piece and a character places 1 log on it, then nothing happens, it just sits there unbuilt and i can't destroy or select it.

ok the only thing i can build is floors, nothing else. nothing.

It seems you lack ropes, which are needed by a fishingrod.

And for blueprints, just click your right mouse, the blueprint will disappear.

Ohhhhhhh ok, thanks, i didn't understand it at first but now i am addicted and it is actually quite simple it was just my nut sized brain can't do anything so lol. Thanks!
