For what it's worth, I installed the steam version, ran the installer for OpenXcom 1.0, and have just been installing the nightlies as they come out. I have the Final Mod Pack, and I haven't had a single issue with this craft. Is the FMP version different somehow? The only other mod I'm using is one of my own make that just tweaks weapon stats, so no conflicts or inadvertent fixes that I know of.
