The only drawback to this is that if the player holds Orel but looses Chotynetz then the forces north of Kursk are still in supply. However since Chotynetz is an objective no victory can be achieved if this location is lost. As such i decided that this was the least problematic solution.
All in all I like the feel of the whole thing much more this way.
Alot of other changes have also been made:
--Changes to objetive turn limits (I am unsure if setting Kursk to turn 5 is too lenient...)
--Added/changed specialists to some Soviet units and re-inforcements
--AI tweaks
--Also changed German supply in the south - breaking up the entrenched infantry should be a very dangerous undertaking now

This new version is uploaded to the first post of this thread.
Any feedback or replays are most welcome!!
