World Grid being called prematurely when trying to update to 1.5

[Arndorferd]

It looks like when I try to create a world with it in 1.5 ExposeData() method which has

Scribe_Deep.Look(ref this.grid, "grid", new object[0]);
Current.Game.World.grid = this.grid;

is being called prematurely? It is saying "Registered RimWorld.Planet.WorldGrid for post load init, but current mode is Inactive."
