Seeing a new issue. ZoC borders disappear, but quitting LH and reloading fixes the issue. Don't ever remember seeing this happen before.
Seems to be linked to the following Debug Message (When said message does not appear, the ZOC will load properly; if said message appears once, then ZOC disappears for all subsequent New Game / Load Game):
Debug Message: Effect 3D7834F8 leaked technique: Draw_ZOCLine_Default Refs: 1
Debug Message: Effect 3D7834F8 leaked technique: Draw_ZOCLine_ClothMap Refs: 1
Note that the number 3D7834F8 changes from one game to another (e.g. 4284D938 and probably a bunch of other possibilities).
