Okay, so here's the problem I'm having; my dwarfs are COMPLETELY ignoring all workshop orders, even orders to dismantle said workshops. b+C building works just fine, and it seems as though my furnaces are sentient because some decided to work and some didn't (even furnaces of the same type). Hauling items also works fine. These problems have persisted as I transferred my save across 6+ versions of DF. Even setting my brewers to do nothing but brew, they ignored "Brew Drink/R" and loafed around with the "No Job" status, same with other professions.
This problem Started around the time several things happened:
1.) I tried to render my fortress in both 3Dwarf and Visual Fortress.
2.) I added the [SOIL_SAND] tag to Loam, because a mood called for glass on a sandless map.
3.) I ordered several thousand (max of ~4000) tiles worth of stone+gems mined across two z-levels.
4.) I ordered ~2500 worth of construction with said stone (Megaproject). Can you job-spam dwarfs into inaction, because I noticed workshop orders are lowest on the job list?
Now, I have a couple other file tweaks in place (no new RAW entries, just a few line changes) and as afore mentioned I'm using the Mayday graphics bundle (the latest one up on his site), but I've had no problems until now.
I'll post more specs and game info if needed, but I'm figuring I just overlooked something incredibly obvious.
