I had something very interesting happen to one of my young forts, Swimarrow. I'm not sure what triggered it, the only thing I did that stands out to me is using the newly added Great Archive. It worked as it should, I was able to use the legends mode in fortress mode. While in legends, I exported some detailed maps to use in Isoworld, and I also ran "exportlegends info" in the dfhack window.
About 15 or so minutes after exiting out of the legends mode, Spring Arrived, and then the
entire map became revealed to me. I could see every vein/cavern/etc. I even got the "Hilarious honking sounds echo from the darkness below!" message. It's important to note I was over 100 z levels away from the nearest adamantite tube. I never even dug into the first cavern. Even so, the first cavern ended around zlevel -28. I've never had this view before so it was pretty fascinating to see the generated area.
At the same time as this happened, every mined out section became filled with whatever material was there before I mined it out except for designated stockpiles (
I think, I could see the grid pattern of the stockpile, but am uncertain if it, too, was filled), encasing all dwarves within the fort. No dwarves were harmed/crushed (although half an elven caravan that just arrived on the screen was instantly crushed to death by a layer(layers?) of sand that appeared on most of the surface. None of the dwarves outside farming were harmed, though most of the animals outside are trapped.
I did not experience any crashing during any of this nor any abnormal graphical glitches. Not even while loading/saving.

Brief (poorly written) summary of fortress events including a brief Forgotten Beast rampage and elven decimation:
The Mystery of *Swimarrow* (based in a small sized world/3x3 embark)
Masterwork mod is used (V1.02 - Newest version as of 5/21/2016 [DF42.06]). Default settings from a fresh download were used.
Swimarrow (Population 49 - 0 Dwarf Deaths) was (still technically existing) a pretty normal fortress, found on the year of 5 in a temperate forest, until one seemingly typical day. Before this, the only interesting things to happen were a few monkey attacks, which ended in about a dozen mutilated monkey corpses. As well as a Forgotten Beast (The Wickedness of Oars) making an appearance whilst rampaging in a discovered cavern.
Luckily the Forgotten Beast had no way of entering Swimarrow because the only staircase was not connected to the cavern (unless there is something out there that climbs on ceilings..or flies). During the rampage he was slain (bled to death) by a rather large female boulder crab named Rampartbraves. The boulder crab is still alive as far as I know. At least the Forgotten Beast got a chance to completely destroy a tribe of troglodytes in the cavern before its death.
There was some sort of freak accident in year 7. About 15 minutes after using the Great Archive I had just built, Spring Arrived, and then the ENTIRE EMBARK AREA WENT SCREWY. The entire map became revealed, I could see every vein, every secret/cavern/etc. Every mined out area, except for designated stockpiles and the surface, became flooded/filled with solid rock, or whatever was there before I mined it.
Most of the surface became covered in a layer of sand, instantly killing half of a caravan of elves that just happened to arrive at that exact moment and trapping the rest. I specifically remember one elf being brutally slammed into their own caravan water buffalo and the entire contents of her/his being exploding into indiscernible gore on impact. Not sure what became of the water buffalo.
Most of the domesticated animals in pasture outside were unharmed, but they were trapped, surrounded by sand. Some dwarf farmers outside were unharmed and not trapped. They have no access to picks and are unable to recover anything from inside the fortress. The outside farms were unharmed, as well as a carpenter’s workshop and ashery that were outside. The farmers are able to access the outside farms/workshops.
The dwarves stuck in stone are unable to mine around themselves and seem to just be getting more drowsy and thirsty. It is important to note that this was not a collapse of sorts.. As far as I can tell. The dwarves encased in stone are not bruised or wounded in any way. No dwarves died during this.
Another fun thing that happened during this was The Circus literally opening up. None of my miners were remotely close to being near it or any adamantine tubes (the tubes are still sealed/untouched). The clowns, unable to unleash hell upon the dwarves, opted instead to start killing each other.
Z Level 0 The "browned out" areas are portions I tried marking around every dwarf to see if they could escape/dig out to no avail.
Z Level -1 This is where the bedrooms, some crating stations, and stockpiles.
Z Level -2 This is where the barracks are located. Archery range and coffin pile were planned to be here.
Z Level -3 This is the location of the temple and the main meeting area, which doubles as a tavern.
