Hm, I just managed to do it, (at least I think it should work this time) but if your editor crashes as you try to edit medals, then that's going to be a problem.
The thing is to set the requirements as Hero variables instead of Global variables.
The problem is that the changes I make in Editor affect the game, but don't seem to affect any files, or at least I haven't found any changes in them.
So, the solution would be for you to edit medals yourself, but as I said, if your editor crashes as you try to edit them, then that's a problem.
BTW, the editor so far seems like it's an Alpha version. It crashes like crazy, which is why I think it's cool that Russians managed to make a couple of new islands despite all the crashes. I also had a Russian version of the game, and it was as buggy as the English one...
