I just saw your thread and well, what to say? I tried to read and compare the comments on the serbian resp english forum and to be honest, I believe mostly of the answers you were given make sense. There has been similar topics/threads like yours, and myself have been in the same situation, like many others.
I don't know how "good" or "bad" footballmanager you are, or your understanding for football for that matter. But things on T11 vs "real life" can't and shouldn't be compared. This is as many already stated - a game - and in a game everything can happen, even the unavoidable. Some of us say quality, stars, tacticts or formations make no sense/impact, while other say the opposite. But since there aren't any clear evidence or study for that matter, it becomes just speculations and our own interpretation.
Now as I see it, you have 3 teams (same lvl) in the same league. Some of us would call it cheating, non-regular etc etc, but since it isn't against the rules/faq, we say it's "okey". And you probably want to take and place them on the 1th, 2nd and 3rd place, correct? Now, in order to make it "equally", the NGE probably decided to disadvantage one of your teams and give the other teams a chance/opportunity to fight for the 1th-4th place. Maybe to encourage the others manager that they still have a chance, despite you having 3 teams. Now, this could be "unfair" against you since you feel that the NGE is working against you - but unfortunately it's nothing you can do about, other than accept the situation.
It's like the saying, "Ne može i jare i pare"
