ok IC2s Crop API has a real seriouse Issue that requires to be fixed. (I can do for my stuff temporary fixes but for the API useage i can not take care of)
java.lang.AbstractMethodError: ic2.core.block.crop.TileEntityCrop.getWorld()Lnet/minecraft/world/World;
at ic2.api.crops.CropCard.getWorld(CropCard.java:381)
This is a crash that is happening when a cropCard tries to access a the world function. The problem here is: TileEntity & ICropTile share the function... So the function name should be fixed... Its a thing that causes seriouse issues.
So please fix it. Even so crops are not done yet properly but it should be fixed in the first place.
