trench warfare
To avoid bad positioning of landforts we could do the following:
"Trench Warfare" fires. It causes series of events - for each province from Belgium and Germany to Paris. Example: Reims is controlled by Germany. The event checks if there is a bordering province controlled by France. If yes, build landforts-trenches. If not - do nothing. I know it is complicated to write events for every province, but we will be sure that the trenches are positioned according to situation. If I am not mistaking this thing can go wrong only if we have completely encircled province, but that is very unlikely to happen.
