Here's the problem as I've seen it and had it described to me...
They make a really cool game, OFP. Everyone loves it and they release a pretty good upgrade, Resistance. Now.. They supported OFP up to V1.46 with a lot of upgrades, but when Res came out, why support the old OFP anymore? From the programmers' standpoint, they have limited time and they are going to spend it on the people that spend money on them... That's what makes the world go round... $ (Not to mention the fact that all the upgrades build on each other, so releasing seperate upgrades for people that have OFP V1.46 would be a nightmare!)
:-\
:-\ Sucks! Change in this game definately has a tendancy to affect detailed missions. Makes it difficult to design missions and get them out before the next upgrade!
I would say you should redesign your mission to where it works from the sound of it... Maybe delete everything you can until it works again, then add back what you removed.
