I didn't see this in the known bugs thread, and it's a minor UI thing more than anything:

I was playing a cakewalk game on a tiny universe with a single enemy (I played human, the enemy was Korx). I've been doing this to learn the tech tree as I never played GalCiv II much and I'm still used to the old tech tree. Anyway, I was doing the culture/influence thing and building influence starbases everywhere.

Each starbase had "1/2/3 modules available" listed underneath the graphic. When I added filled one entire module "branch", the interface would update correctly (going from 3 to 2, or 2 to 1). If I researched a new module that went into the previously filled line, the starbases would not update (from 1 to 2, or 2 to 3) until I clicked on them directly. So even though two modules were available to a starbase, it would say only one was available.
