I just double-checked and the humanbred troops cost 13 gold apiece. They range from 11-30 resources in cost, depending (of course) on equipment.
I play with dragons a lot (I just like 'em
) and I haven't seen the weird name thing, or at least didn't spot it if it happened. Could it be related to a demo-specific issue, such as a pointer being out of place due to a shift in content layout?
There's no centering key (it'd be nice if right-click would center though - hint-hint!) unless you count Home centering you on your home province. You can hit # and then type in a province number to center there immediately, but I've only used that to test it. The way I do it is to either use the Center on Province option from the relevent news-of-the-turn entries (i.e. Messages), or use F1 for the super-handy Nation Overview.
Tip on Nation Overview, BTW. You can hit Tab to toggle commmander display. I often turn them on to check orders, turn them off to check provinces, and so forth. You can also hit Tab on the Army Set-up screen to hide Researching commanders. (It'll tell you in a line on the top of the screen how many hidden researchers you have in that province.)
