I need a clarification on what is actually happening with supply access.
Here's the scenario
1) Multi-Player PBEM
2) Russia is at war with Prussia
3) France is moving through Prussia with foreign access to Warsaw to support Prussia using Foreign Access
4) Supply isn't flowing either through Prussia or from Prussia to 2 French Corp and Nappy. Their supply is dropping at an alarming rate. About 3 turns into moving through Prussia and they are already almost out of supply.
What is supposed to happen here? From France -> Hannover -> through Frankfurt is fine with supply depots/etc. Frankfurt to Posen needs a little help but the build supply depot RGD doesn't seem to working yet in Prussian territory.
