Basically, you're just locating everything in game that points to that area of data. Since we moved it, it wouldn't make sense for it to point to that data anymore. We want it to point to our new data.
So by "Finding" the old pointer, we are going to change all of them to point to our new table location.
The reason we search 04 0c 25 08 is because that is a pointer to 0x250c04, aka where the old table was.
In your hex editor, scroll all the way to the top. Then press the find button, search for the old pointer (make sure it's set to "search down" on the side there). For every one you find, replace that pointer with your new pointer (wherever you moved the table.)
Keep doing it until there are no more pointers to the old table.
