I've tried to select saves that indicate where I think the bug is happening; I can't guarantee these are all from the same save progression as I made multiple saves over the play time, but I've isolated the rough issues I hope.

"Raid Bug Report 01": Pre-issue. All the Squads: Knives, Picks, Hammers and Humies are ok and there are no dwarves stuck.

"Report 02": The Knives have bugged and 9 are missing. I cannot recall where they were going or what has been done since they were sent. There are multiple past mission Reports still listed on the World Map

"Report 03": The Knives have been replaced, and will return from the mission they're currently on. If nothing is done on this save, the Picks and Hammers will all return by the 12th Granite. The World Map still has all the past Missions listed.

"Report 04": In the middle of a Goblin Siege. Combat orders during the siege might have been issued; World Missions have definitely been cleared since 4. If save is untouched, the Picks are going to a mission, and the Hammers returning but neither complete, leaving 8 and 9 more dwarves bugged.

"Report 05": After the Siege, likely from a reload. The Picks are home and so were in a different state at some point and are now not on a mission, the Hammers are bugged as in Report 4. World Missions are cleared also as in 4.

"Report 06": Likely from the same playsession as 4. The Knives (with replacement dwarves) mostly will return from the current mission, although dwarf Dastot Muthkatudor seemed to get stuck Travelling in one watch. Picks and Hammers are still stuck as in 4.


So to summarise my thoughts; the Picks and Hammers are breaking during the period between Save 3 and 4, and there are two obvious culprits. It might be cancelling all the Missions listed on the World Map (probably done to try and get them back to fight off goblins quicker) as they clear between the 2 saves. Or by giving orders on the Fortress map after the siege starts to the Squads when they had individuals still heading out/returned on the map but the rest of the squad wasn't there. (Attack that goblin, positioning them to defend etc)... that confusion for me came because the dwarves move at individual speeds on the game map, and the new UI shows them as returned from a mission when some (first? Squad leader?) gets back to the map but the rest are still in a Travelling state, likewise you can cancel the mission when some, but not all have arrived at it? And I didn't look too closely at the whole squad state when fighting off the goblins.

There are probably also less obvious triggers, such as when on some repeats of 06 that a single dwarf seemed to potentially get stuck...? But I couldn't narrow that one down, likewise I couldn't match up the Knives breaking and losing the first 9 dwarves with any particular moment.

Hope this helps!
