redownload and replace

you know, I am starting to have nightmares (
exaggeration!!!) about FH2259.
Sure it's a cool campaign, sure I am still not sick of playing it
BUT it's also my first work. It contains the first mission I ever fredded (in fact, it contains the first 9 missions I ever fredded

) and I would do a lot of things differently now.
As a beginner's work, it has all the little glitches, problems and bugs of a first work.
I got rid of the most by now but until I redo the whole campaign from scratch (which will never happen because I don't want to and because I am to lazy), something will go wrong all the time.
