Poland/GDoW is in the French alliance straight away so supply and access are available.
Interesting to note that teleportation only happens in regions with a structure (including depots) it looks like this is the game engine processing the change in in ownership (GDoW is a completely new faction controlling a region/structure not a reversion of an occupied region/structure back to its previous owner) and not a fault with diplomacy as in previous script (Tilsit, Pressburg).
Game engine needs to allow allied stacks to remain in region/structure after ownership change from Prussia>GDoW (infact in this case it also should allow hostile stacks to stay because the GDoW is not yet diplomatically reconised by the other belligerents).
