My item damages for ONE SECOND and then goes right back to being damaged. You'd think it has something to do with client server syncing but it isn't as it is called on both sides.

 

object ItemWateringCan extends Item {

  setRegistryName(DrugMod.modid, "watering_can")
  setUnlocalizedName(DrugMod.modid + ":watering_can")
  setCreativeTab(CreativeTabs.TOOLS)
  setMaxDamage(20)

  override def onItemUse(player: EntityPlayer, world: World, pos: BlockPos, hand: EnumHand, facing: EnumFacing, hitX: Float, hitY: Float, hitZ: Float): EnumActionResult = {
//    if(!world.isRemote) {
//      val blockState = world.getBlockState(pos)
//      if(blockState.getBlock == Blocks.WATER) {
//      } else if (blockState.getBlock == BlockCropPot) {
//        world.setBlockState(pos, BlockCropPot.getDefaultState.withProperty(BlockFarmland.MOISTURE, 7:java.lang.Integer))
//      }
//    }
    println(player.getHeldItem(hand).isItemStackDamageable)
    if(!world.isRemote) {
      player.getHeldItem(hand).damageItem(1, player)
    }
      super.onItemUse(player, world, pos, hand, facing, hitX, hitY, hitZ)
  }

}

On the post I tried just server to see if it would help and it did not.
