@User: Not a big deal; the random seed is used to add a prefix to cells in the user project to ensure that they are unique and do not collide with cells used in caravel/caravan. I think the foundry does the same thing when composing the reticle, so it doesn't really matter if all of the user projects are using the same prefix. But the intent was that by tying the random seed to the user project number, each user project would get a prefix that was both unique and repeatable.
