Alright, I've nuked the code that deletes grid entries and grids as there is no filter on version that is honestly necessary for this.
Even if I joined tables on the NPC's that are imported there is a high possibility that the gridid may potentially conflict so deleting doesn't make all that much sense.

I've pulled on live EoC these changes, so you should be good to go
