I need help. I was working with ed42 creating my map, everything was working nicely, no errors etc. Then for some reason my map from ed42 stopped opening (the game wasn't starting). I moved to bc42, here everything still works fine, but its so hard to interact with objects, so I want to go back to ed42 and solve the error.
What I tried was: I took vanilla map which was ok, unpacked with BGA and packed again, not changing anything. after that the game didn't open. so after this I thought it's some problem with packing because the map is absolutely the same as before
So what might be the problem and how to solve it? I tried packing/unpacking with winrfa, deleting all stuff and pack/unpack with clear game, didn't help


(by the way, while I try to open unpacked and packed vanilla map with bc42, it says 'missing key files to successfully download'. maybe this helps)
