OK, after carefully testing it in debugmode, I believe, the problem has been solved by you. =) Thanks for the work. I'll add it to my patch-files. Just one additional question on that topic: Do you think, these files will be usefull for ufo2000-maps as well? (Maybe Hobbes can shed some light on that, too...). It relies on vanilla-files, as well. But I don't know, if these bugfixes on the maps may be benefitial to it, as well.
