"You do have the mod directory defined in FRED?"
What exactly does this mean? All of my other modified tables - ships, weapons, music - have an impact on FRED2; i.e. when building a mission I can select my modified weapons, ships, music tracks. But for some reason, this is not true for my ai_profiles.tbl, which is in the exact same folder as all the others. Mission Specs reads FS2RETAIL as my only option, and that seems quite impossible as I've deleted that profile entirely. This is build 3.6.9. I am really quite stumped and it seems insane that I can't figure this out!
