I cannot add new recipes involve IC2 items.

[kice]

There are also some other recipes can successfully add to the server.

Those recipes I can add them when I play solo but cannot be added to server.

recipes.addShapeless(<railcraft:nugget:3> * 9, [<ore:ingotTin>]);

recipes.addShapeless(<ic2:crop_res:2>, [<forestry:fertilizerCompound>]);
recipes.addShapeless(<forestry:fertilizerCompound>, [<ic2:crop_res:2>]);
