When you train your bridge officers
Is there away to get the old albities back

Other than retrain them? No.

When you train a BOFF in a new skill, you're completely and irrevocably replacing the old skill.

Thanks for the reply sucks that you can't retain the old skills

But whats the point??? The only reason why you retrain is that you didn't want the old skills.... If you want both the old and new skills, then you get a duplicate BO, and swap as needed...
