Design with Logic Lock region cannot fit anymore Error (18999): Placement cannot find a legal solution

Hi, I have a design using two logic lock regions for timing optimization. Unfortunately Quartus would not fit the design when I assign the entity to the LL regions throwing this error during fitting...

It's ok, try to make it larger and let us know how it goes. Another way is let the logic lock float. Quartus will decide how large it need to place. thanks
