Please guys don't debate over law, SS or censure in this thread. This is not the place for that. There will be no SS mod made by me for DI:G.
1. Copy the HOI3 entire folder (+SF+patch+DIG) to your desktop. I said copy, so you have 2 HOI3 folders now.
2. Now go back to the old HOI3 and copy the entire \mod directory
3. Paste it into the new HOI3 copy, overwrite the files.
I suspect there is a conflict with creation dates or something within vanilla and DI:G. If you copy DI:G over itself it may make DI:G newer than vanilla files and then the game will take DI:G gfx and the bug would disappear.
Since I can't reproduce your bug I can't help you more than that. Please be sure your follow the exact steps and report back.
