I can't open DH back up with the error still there,but I just remembered that I used the arrow key to select ignore.Thanks anyway.
EDIT:Ugh.Poland took control of Berlin,so the German surrender event wouldn't fire.So I had to fire it manually,which led to complications such as Poland still being at war with Germany and taking over,but not making peace.
The save game problem happened to me as well on one occasion. It's my fault actually
The bug usually happens when the modder makes a typo in some file which doesn't cause a bug at game start. He then saves the game, the game copies the bug onto the save file and then can't open it because of some misaligned parenthesis or quotation mark in line 2354. Ah, the wonders of modding
If it happens again, upload the saved file somewhere and I'll track the bug for you.
The German surrender bug will be fixed for the next release.
