The mayor got un-stressed after about a year of staying out of the rain, then went back to stressed without showing a negative thought. I _think_ he got involved in the re-make of Revenge of the Return of the Buzzard Clusterfuck. Those events cause a vengeful thought that gets scrubbed from thoughts almost instantly but seems to have the full impact on stress-prone dwarfs.
As a little bonus, a sheep ended up in a tree. One of the farmer's workshops lined up a milk animal job for it, but no-one felt obliged to help her down from the branches. I ordered a ramp and wall built adjacent to the tree when she went into starving status.
To keep my beards capable of doing outside work at normal speed (instead of puking their stomachs out and crawling about at 1/5 normal) i built a statue by the outside barracks and made it a room. The children love partying there and paint it a lush green. Seems that cave adaptation is ridiculously hard to lower.
Fiddling with Cart-Door Logic, the easy ability to do bifurcation on more than one axis (splitting minecart paths coming from e.g. two different possible input directions into a full four output paths) opens some pretty crazy avenues, like two-door D-Latches or a single-door-single-plate double-action edge detector.
Lolwut?
Double-action edge detector: a device that sends an on-off signal _cycle_ everytime its input _changes_. With only one plate, it sends the exact same signal cycle in either case; perfect if you want to start some machine with a lever flip but want the state to reset to neutral after each operation instead of running on forever (or until Urist goes off break and decides to reset the lever). In double-action mode, you can release a minecart projectile or dump a goblin on _every_ lever flip, regardless of direction.

Simple, no?
While the door is closed, the cart is in the southern loop, constantly kept at maximum ramp speed by the three impulse ramps. When the door opens, it passes through, touches the pressure plate, turns around east and switches to the northern loop. It enters the loop and stays in it because it's too fast (and the impulse ramps keep it too fast) to care about normal corners, and its speed of well over two tiles per step means it never again touches the pressure plate after the first passage. When the door closes again, the cart can't pass the door and takes the corner instead, gets funnelled over the pressure plate once again and, thanks to its high speed, completely ignores the corners and opposing impulse ramp on its way back to the southern loop. Tried and proven.
