Hello everyone
Since I just registered now, first I would like to express my thanks for this great mod and all the effort that is put into it.
Now I hope this is in the correct section. If not -> Pleae point me there and I will be on my way.
Unfortunately a friend of mine and myself discovered a problem with the agricultural part of the mod, which is the fact that we are not able to plant crops (the sticks) on farmland. They immediately disappear and reappear in the players inventory.
This issue can temporarily be fixed by replacing the level.dat in the "saves"-folder (I'm starting the server out of singleplayer when my friend wants to participate) with a fresh level.dat taken out of a recreated (via the "Re-Create" function in the singleplayer menu) savefile. Sadly this workaround only works until the server is closed and reopened, which results in the same problem I described earlier. (Also using this workaround all the time is a bit annoying since the hosting player always has to start without his equipment (Can be worked around with NotEnoughItems) at the spawn point for new players which is... quite far away from our constructionsite.)
I hope someone can help us out. If you need anything more, like a list of the other mods we use or anything else, I will do my best to provide the relevant information, but since I've also got some other matters at hand it might take me a day to come back here and reply again so please be patient with me 
With kind regards
Nagard
