I think the problem is on my end. Therefore, I'm redownloading DF and trying again. If this doesn't work, I'll hand off to the next biggest party (which, if I remember correctly, is 4mask). I think my DF copy is fucked up in some way, because the filesize is currently way smaller than it should be.
EDIT: It works. I'll commence my turn tomorrow.
As of course is customary, I shall now critique the preceding player's turn and not give them credit for any good things they've done.
First off, damn that is a FUCKLOAD of chopped wood lying about on the surface. Urist McWoodcutter is desperate to win an election for the underappreciated woodcutter's guild.
Security topside is good - only problem I have is that the atom-smasher area has no roof, and can't be sealed except with a door. If we get a flying titan, it can path into the fort. This is a bad thing that might make the fort entertaining and not just dry and hyper-competent. I must fix it immediately. Security in the caverns could be improved - currently something can path into the fort from the magma sea, and we're wide open for anything that can avoid a cage trap (or anything that comes after 2 other cages traps have been triggered). I have plans for upgrading this.
Basically; I'll disengage our current infinite mining pattern and focus on expanding the fort proper; making it secure and comfortable, etc. If anyone has any requests (other than 4mask's Guild Hall) you should probably state them now.
EDIT: To be completely honest, our current design makes little sense to me. I'm considering abandoning the upper fortress and carving out a new fortress just above the caverns. Maybe that's being overly ambitious with 22 dwarves...
