new problem:
I think my mercenaries are messed up.
First occurrance was a couple days ago after a game as Carthage.
I can only put units up for sale until one gets hired. Once one of my units is hired, I cannot see any of my units contracted out, or the one that got hired in the screen (sometimes, of course, the mercenary is killed, but other times, the Financial advisor screen says I am still getting GPT for hired out mercenaries...and that says nothing about all of the other mercenaries I have contracted out that just dissappear in the screen.)
Also, I can only hire mercenaries once. The turn after I hire a mercenary, all mercenaries dissappear...even my own contracted out. (Of course, there's a VERY SMALL possibility that there just aren't any mercenaries to hire...but I seriously doubt that this has been the case for my last 3 games.)
I will attach an example as soon as possible.
EDIT: Sorry, it must have been just an isolated occurrance... It seems VERY UNLIKELY that there weren't any mercenaries for three straight games, but now it seems to work again...
