"A" is probably the source of your problem. For now, open your mod and right-click in the left window. Change the .pack type to "mod". See if that fixes your problem.
I assume you've already read my tutorial on creating a mod. In the future, start your process like this:
- Create a folder called "extraordinaire_mod" or whatever you like.
- Open patch2.pack with PFM.
- Right-click on the tables you'd like to modify and "Extract" them to your new folder.
- After you've extracted all the file you want, click on "File>New" in PFM and select your new folder as the folder to make your mod relative to.
- Then add the tables you just extracted. Save your new .pack to the folder you created and start editing as described in the tutorial.
