Forestry multi-block tree farm won't work on one side

[MFINN23]

It's a 3X3X4 managed multi-block tree farm (the default). It won't place humus or plant trees on one of the four sides. I tried placing the humus manually on that side after it didn't work and still won't plant. Broke a block then replaced it to reset the multi-block and that didn't work either. Anyone else having this problem? Can't seem to get it to work.[DOUBLEPOST=1360504318][/DOUBLEPOST]Using the direwolf pack, most recent version.

Started working finally. Took hours. I think the problem is that the farm checks if there is farmland as it's absolute last task and as long as it has another task then it doesn't do it. If I make another one I'll be putting in saplings last after it has placed everything.
