Addendum:
(Note: I meant to have put this as an addendum to the previous post.)
Decided not wait for a reply. I knew this wasn't right. So, I took my own advice since this was kind of a major issue.
1. I uninstalled FPS Creator and MPs (I have more than 40 of them).
2. I backed up the rest.
3. I deleted the FPS Creator directory.
4. I ran a safe clean on Windows Registry.
5. I re-installed FPS Creator v1.0 from disk.
6. I installed v1.17
7. I tested the destroy fpi on a character. (Worked like a charm now).
8. I installed v1.18 beta 10.
9. I tested the destroy fpi on a character. (Worked like a charm with this version as well).
10. I installed RPG Mod.
11. RPG Mod works. The mod contains beta 10+. All the source code releases after official beta 10 release.
12. Installed Bond1's MP #52 and the characters work even better now.
So, I now have clean bill of health. Happy day, Oh, happy day.
