Newbie here, need help resizing a Sulani lot on S4S Wishes

The creator re-published their tutorial here with pictures, but it's lacking in some info that will cause issues for those unaware. When you go to edit the sizes, they are not plain numbers and actually in hexadecimal.
Here are the lot sizes as the correct values:
14 = 20 in game
1E = 30 in game
28 = 40 in game
32 = 50 in game
40 = 64 in game

So an example, to make a lot 64x64:
LotDataSizeX would be 00000040
LotDataSizeZ would be 00000040

OR

To make a 20x30 lot it would be:
LotDataSizeX would be 00000020
LotDataSizeZ would be 0000001E

Also:

• Making lots larger can cause terrain clipping (such as on/nearby hills), especially if you use the terrain tools.


• You cannot go higher than 64x64, it will crash the game if you do.


• Making lots smaller will result in holes in the world, same if you move them.


• Making lots intersect will cause issues with clicking on the ground (where they intersect you will always get the option to travel to the other lot).


• You will need to update your lot sizes every update (or almost every update) as the game replaces those files when it does (especially because EA updates worlds frequently). While you can copy/paste the one from your workspace to save on work, eventually you'll need to re-do it from scratch to avoid any issues.
