Okay i've read a couple more walls of text and i think it's gonna be fixeable not too hardly.
Just, it feels like it's gonna take at least a whole weekend and i don't know yet if i can spend that much on sthg else that studying atm.
Good news is that apparently, the return bug (a JASS tool used in advanced maps like CC but not Rival Dynasties neither Goblin Dominions, so they should work perfect) was destroyed, but only to add new features that basically do what the return bug used to do.
So CC is temporarily dead, until i rewrite all the code that use deleted tools, like that return bug.
