The Starbases list has a cousin problem to the one in the Notifications list. It isn't a flickering thing, but the response to the filter choices is erratic.
Sometimes filtering for Shipyards works, sometimes it doesn't. The most common pattern I see is a good result on first use, followed by a stretch where I have to click Shipyards, click another filter, and then click Shipyards again. Occasionally after the problem has 'activated' it goes away for one or two 'instances' but it always seems to return.
And since folks are talking improvements here, I'd like to second
Traded technologies should not lock down specialisations
Rename specialisation technology names so that you can more easily recognise the specialisation , e.g. Kinetic Weapons Improvement II: Manufacturing Costs
Add visual Feedback on the Diplo screen (e.g. an icon next to the planet, or a circle at the base point), so that you can tell at a glance which race you can trade with (lack of this is currently holding me back playing with more races)
In addition to a bit more info in the UI, I'd also really appreciate some context menus in the management windows, e.g. right-click-->Make Obsolete in the Designer, and a general pass for 'sticky' settings in lists, e.g. the filters in the Starbases list and the turn-span on the Timeline tab. Some thoughtful context menu additions could go a long way towards lowering micro-management overhead for those of us who love the Ludicrously Large and Long games.
