Once you have completed all the updates to the item definitions, if you've modified the marketable or tradeable flags, make a call to
FlushAssetAppearanceCache to immediately update the state of the associated items on the market. This call executes an expensive server operation so should only be done after all updates are completed and only when these flags have been modified.
