So this was actually an innate problem of the current engine, not a problem of a single mod. Some good and stable features of the openXCOM extended really should start being incorporated to the mainstream: the opportunity cost we're losing is getting higher every day, really.
I couldn't understand Falko's suggestion though. Even though it is a 'corpse' technically, anyway we regard it as a 'broken armor' and represented as such in the game in most mods, right? (I haven't seen something like 'a corpse with flying suit' in the selling screen
) So why such an 'ethical' concern should be considered? Maybe I didn't understand because I'm not fluent in English... Sorry for that in that case.
