Save where dwarfs will keep getting stranded whenever the environment changes (e.g. building walls/floors, mining etc.) - dwarfs building will build a wall and then immediately get "stranded" next to it (shows up on DFHack as stranded) showing no job and standing still. With mining the dwarfs will mine the tiles which they can immediately access, and then ignore any of the tiles behind that (see elevation 24 where I am trying to make a burial room after a !FUN! incident). Both issues will persist until the save is reloaded (returning to main menu, and loading the game again).
