Seems as if the Ironhand graphic set is experiencing some issues. It doesn't load for the menu or for world generation, but once you get into game its magically Ironhand graphics.
I personally like ASCII in world map. I honestly thought that was a feature of twbt. Is it not?
Yes, the ASCII world map is a deliberate feature. There was some discussion a while ago of supporting a third tileset for maps, but it never went anywhere
Is there a way I can disable all DFhack functionality EXCEPT TWBT?
Delete
dfhack.init and the other dfhack init files; keep dfhack enabled in PyLNP but don't select any of the options.
Is TWBT still causing crashes? I'm trying to use that again and suffering crashes again...had disabled that and gone to 2D instead on prior versions when it was suggested that TWBT had issues.
TwbT is always crashier than vanilla, but the specifics really depend on the details of your computer. Unfortunately this makes it very hard to troubleshoot or give specific advice!
Uuh ... I just got a "Fatal Error Missing Color Definition" ...
Try reinstalling the graphics pack; if that fails replace "$df/data/init/colors.txt" with the same file from vanilla. I've not heard of this specific issue before, but it sounds like that file is incomplete so it should be recoverable.
