When in the civiliopedia entry for Landsknecht, I get a persistent CTD when clicking the hyperlink for Pikeman.

This is a bug that was created by patch 3.03. All the civlopedia links have a high probability of causing a CTD when clicked under this patch. BtS 3.02 doesn't have this bug (or the combat animations bug from 3.03). There's a new patch due soon (3.13) which should correct this as well.

Good thing! Thanks for the info :)
