Running my fort, i have several frustrating things that i can't seem to work out.
1. I've built 2 bridges for my fort. I built them, linked them to levers, tested them, they worked fine. Come the first siege, i pull the level, lever switches 'on' the bridge. I wait eagerly, like 10 seconds... nothing happens. Seems they just, really don't want to work. No trolls or anything heavy has ever stepped foot on the bridge, the bridge is clear, there are no objects on it. I've tried redo'ing, still nuda. Is it a burrow issue? I've tried including the bridge within the burrow. But no.
2. The goblins be-sieged.. they only had spearman and a bowmen on a bat. Is it in anyway possible that they can mine through a wall? Becuase instead of going towards my now open gates, they made a hole into an earth wall. That hole linked into a chanelled area that was part of a plateu, so now they could just walk in the back way into my base. No Problem. I'll just deploy my 40+ military to the breech. I set them up in anticipation. The goblins halt thier advance, the bat-goblin seems to be stuck (

). OK whatever. I dismiss my military back to training (lol). To be double safe, i build a set of doors in a tight corridor and then lock them. Cool. Should be ok? Nope. My civillians are behaving, but one of my military dwarfs instead of going back to training (like everybody else) decides to rambo randomly. But i've got the doors locked right? Nope. HE WALKS STRAIGHT THROUGH THEM, as if their not locked then gets killed. -__-
3. In every menu (except the opening one) i view whilst playing the game. Random parts of text seem to missing/blank depending if i scroll over them or not. It's minor, but it's annoying, any explanation to that?
ps im running windows 7, on a decent computer, so it's not lag related.
any help appreciated, thx
