Notes

Edit: It wasn't neccesary to copy the entire game folder, just the save folder is neccesary. As for where the stray drake is, it's the only one in your fort and you're pratically looking at it on the spot where the game loads, it's the only unit in view with a flashing '?' Edit2: Yep, crashes for me as well about or within 10 seconds of unpausing. The errorlog: Problem signature: Problem Event Name: APPCRASH Application Name: Dwarf Fortress.exe Application Version: 0.0.0.0 Application Timestamp: 5419c537 Fault Module Name: Dwarf Fortress.exe Fault Module Version: 0.0.0.0 Fault Module Timestamp: 5419c537 Exception Code: c0000094 Exception Offset: 0078131d OS Version: 6.3.9600.2.0.0.768.101 Locale ID: 1033 Additional Information 1: 5861 Additional Information 2: 5861822e1919d7c014bbb064c64908b2 Additional Information 3: d1d9 Additional Information 4: d1d94a13d3609d6b740644c12508f581 No idea how to make it show the detail as the OP, I'm using windows 8.1 or whatever the latest version.

(0030559) smjjames (reporter) 2014-10-06 19:40	Okay, I checked if the drake had anything to do with it by killing it via DFhack, still crashes. It probably came with a migrant wave and you just didn't notice it. At least it's a reproducible crash, no idea where to look for the cause.

(0030570) CaeDares (reporter) 2014-10-07 14:09	Sorry, I notice it now. I guess in my frustration to discover the problem, I kept overlooking him. Thanks for taking a look at my save, however. My bad on giving you the entire game. If it helps at all, something buggy was going on with my dwarves. I have a bunch of stuff designated to go into my Dump pile, but for some odd reason, some dwarves will try to grab those items to use in Metalwork or Masonry, doesn't really matter. There was a point that I had 3 dwarves at a time doing it. They go to grab it, and once they're over the object, they stop moving. They'll stand there until they die because they're rmtrying to obtain this item, but its designated towards the dump. The item doesn't even appear under them (even though it shows via flashing) until I cancel the job they're working on. Would that happen to possibly be a cause of this problem? This is also the first save I've gotten where all the barrels and bins actually work, (my mistake for giving each pile a "reserved" amount) so if there's a way to save this save file, I'd appreciate the knowledge.

Said weasel appears to be just over 10 days old, which would normally put its body size at 2 (due to [BODY_SIZE:0:0:20]); presumably, random genetic variation caused it to be "smaller than usual" and reduced its body size all the way to zero. If you have DFHack, type the command ":lua df.unit.find(1001).animal.vanish_countdown = 1" and then unpause - the weasel should vanish in a puff of smoke (just like a bogeyman) and the game should continue without crashing.

(0030572) smjjames (reporter) 2014-10-07 21:53	I saw the OPs full game save that they put up, he/she doesn't have DFhack. However, canceling the cooks hunting job should do the trick, although might want to cancel the other hunt jobs and turn off hunting for at least a season until said baby weasel leaves the map. You could try siccing the military on it, but no telling what will happen, might even crash again.

(0030583) CaeDares (reporter) 2014-10-08 18:10	I installed DFHack and took care of the pesky weasel. As much as I'd like to have obtained him, he is now gone and my fortress is now seemably crash free. Thank you for your help!
