Sometimes supply will straight up go to 0 if you push a single province into the enemy lines, despite that this is still part of your front line.This leads to supply screw or completely routine surround on a completely arbitrary basis of supply region, despite that the tactic is identical otherwise. Main culprit is "% adjacent controlled", which can be inconsistent once game also starts factoring regions. Supply will go from 20+ to Routes sometimes flip between good and bad supply paths, despite no change in availability of either (no convoy raids at sea, no significant infrastructure/damage or bombing).100% is going too far, but it is really bad/buggy.
