Missing model in ToyBox

I set my entity to require TF2, but it seems that there are still some people who are missing content from Harvest.
( [!toybox_3646_94:83] Model missing: models/harvest/pumpkin/pumpkin_big.mdl )

Is it possible that their TF2 was somehow mounted, but it never included any of the harvest updates from over a year ago? This model isn’t even the halloween one, it’s just a pumpkin.

Some people say that they can’t really use the ent because of this.
