made a villiger powered wheatfarm(breadfarm) in singelplayer and it worked fine, but when i built a copy on my SERVER the lightlevel on the farmland bugged out. I use a pressure plate to "pop" out the seed when the villiger walks over it and this dont seam to work on the server.
i need a light level at 7 on the one block inside the farm for it to work but i can only get 8(or higher) or 0. so you can either plant crops or you cant because its to dark.
Unless you can pinpoint the actual bug here, there's not much we can do.
