Just upgraded to 1.3. Still not working properly.
Are you sure there isn't some kind of invisible block?
Is not the first time some kind of invisible light sources block farmlands. check if you can actually place any other block in that spot
Also, regarding the Sprinker lag, it turned to be not the sprinker themselves, but the sprinker trying to keep the farmland hydrated.
Just placed a water source block where there was before and got to the fps levels I had before. However thanks to NEI now I know I can use humus instead of farmland meaning I don't need any water source blocks.
I want to try the tilled garden soil but in regrow I can't until I get the traumium hoe, assuming it works, since TiCon hatchets won't work and the right click manasteel shovel neiter. But that's a Garden Core issue
Anyways, is there any difference in terms of grow between using farmland, humus and tilled garden soil?
