Anchor key saving a big grid has significant performance impact

[oooielp]

Saving a large grid can cause significant performance impact & lag spikes.

Perhaps this could be addressed through batch-saving a grid. With with method though there is the obvious risk of item duplication (what if I withdraw all my money, place it on the corner of the ship that starts saving first, and manage to move it during the save so that the item saves twice?)

I think this could certainly be addressed, though it probably needs more thought
