i had the same problem yesterday. i was moving forts when the site booted me for maintenece and since then i was not able to move items on my maps. i have not tried today though
I've sent a message to the GM and things should work fine by now, not unless they are doing it individually. Send messages to the GM if you are experiencing this problem, Meaning you can't relocate objects and your not in a war.
I have also similar problem than this if I go to war I cannot choose targets. If I click map nothing happens if I click choose targets menu nothing happens. I cannot even write targets name in dialog box its locked.
An update as going horrible wrong again. Too bad W3C dident bother to check up this forum after they did update... its usually a good idea. Hopefully they fix this tomorrow.
