I'm still trying to finish my v1.31 game so this issue may have been addressed in v1.4 but I thought I'd bring it up anyway in case it hasn't.
In v1.2, when you reloaded a saved game, your influence area would be in a default state. It wouldn't be until you hit the turn button that a new ZOC (zone of control) calculation was made, restoring your influence area to it's pre-save state.
In v1.31 your influence area is still set to default on the load of a saved game. However, it now seems that the ZOC is not recalculated by end turn. It seems that it's only when you capture a new planet or create a new starbase that a new ZOC calculation occurs. This means I can go many turns with incorrect influence areas.
This is both annoying and can cause undeserved wars. I’ve had the AI declare war on me because of my ships being too close to his borders, when in fact if the influence areas had been recalculated, none of my ships were within a sector of an AI’s influence area. At the least, the "we know what you’re doing" cause for war should be suspended until the ZOC has been recalculated.
