I am currently trying to update and fix a broken CE table, while I managed to easily fix ones using AOB search, some of them turn up nothing now.

I don't know how I can go about finding the correct area to fix them, as searching for the original AOB as I stated earlier, turns up nothing.

I've attached a picture of one of the scripts I am trying to fix that I am unable to find the AOBs for.

I am still relatively new to CE and trying to figure it out.

If anyone can help that would be awesome!

It will vary depending on how much the game has changed since the table was made as well as if they changed/updated the tooling (ie. compiler) and such since the game was built when the table was made. Fixing something like this can be as easy as adjusting the pattern to not include object/structure offsets, but it could also be as bad as the compiler has now reused entirely different registers/opcodes for things.

You can try and adjust the pattern to not include the hardcoded offsets (ie. 1C and 20 in the example you gave above):

Change:
8B 7A 1C 48 8B 42 20

To this:
8B 7A ?? 48 8B 42 ?? 48 89 45

And see if that pattern turns up with anything. If not, then you may need to try other parts of what code is available from the past version of the game seen in the comment block of code in the bottom of your screenshot. See if you can find other parts of that older code instead of the original injection point itself.

Do you know which part I would have to change if I happen to find what I am looking for? I don't have much experience with symbols.

Edit: so far nothing has weilded the result I am looking for Sad
