I found one strange thing. I once checked all this case on Il-2 4.08 a couple of days ago, and created a campaign there, everything worked, just beta-tested )
But when I slipped him a fresh message_ru, launched DCG and accidentally clicked on the "Create Player Defined Campaign" icon, an error like this came out:
"\uxxx"...
I closed it and decided that it was a conflict of old files and started it again and there was no more error.
So, maybe the [Errors] section did not need translation? I cannot now reproduce the error to check
