Need a little help knowing , will the items players have crafted and use as decor de spawn if the Randis Halloween Mod is removed?

We're not having any issues at all with the mod it is excellent, but the discussion of if we end up removing the mod will players lose items they already have has come up and we don't know what to tell them as of yet.

If they were able to keep such items, this mod could be used for events and holiday and the players who participate end up with rare items no one else can get later on. Which is really cool.
