During the battle for the boots of the spider (lift the lid, etc.) the hoarder spider attempts to summon, then the game will not proceed.  Hoarder spider stays highlighted (on its turn), I can click anything, select units for more info, etc. but the battle will not proceed to the next creature/player.

Related:  I'm always amazed at any company's poor communication - how long does it take to write a post once a week saying "this is what we're working on" fixing bugs, enhancements, etc.  This forum gets a tiny amount of traffic - respond to each post, Stardock.  I've had good vibes for Stardock since GalCiv I (on OS/2, no less) but you guys have really screwed the pooch on this game.  I want to love it, but c'mon, you know this shit is broken, a lot of stuff has been fixed by the modders - grab those fixes, check them out and shove them into a 1.5x revision *this week*.  Next week do the same with whatever little bugs you've squashed.
