Comment 4 for bug 988870

thanks for checking!
so on one line it should be
"return=skipped unless economy needs cloth and not economy needs thatchreed"
right?

in other words:
skip always but not when you need cloth and at the same time you don't need thatchreed.
if you need thatchreed, skip
if you do not need cloth, skip

This is "how to do" it, but let's see "if" we want to do it.

Time ago, I've opened a similar topic here: http://wl.widelands.org/forum/topic/922/ where I found that the same behavior you describe is valid for cattle farm, too.

It seems there is more logic than it may appear at first look, but I've not got it yet :)
