Preservation level: Final leads to Quartus crash on re-run

Auto logic lock was giving stacked locations (well I did not ask to reserve the region either so Quartus can do that),

but I'm wondering if this is not counter productive.

So my question:

Shall the final snapshot work better or not with logic region or is that not relevant?

Or shall I use the logic lock with reserved ?

I will try with reserved and without partition to see how that goes with final.

Let me know what is expected.
