1)In every save i essentially get to the point when dwarves assigned to plant gathering zone get stuck. They just gather plants indefinitely (no gathering happening).
I suppose they try to pick up plants/seeds or whatever which can not be picked (like pine cone seeds or in this case, cherry flowers).
Turning off gathering with stepladders and from the ground generally fixes, making dwarves unstuck.
[2)Another, bug note ive encountered (not in this save) is marxdwarves getting equipment mismatch when assigned different bolts for training and combat (idk why)
And also, when carve out fortification and find demon the dwarves behavior is getting bugged, they just encounter hostile creature and stand still forever. Ignoring dehydration, thrist or anything, they dont attack either and there is no way to move them from this situation beside dfhack. (disbanding squad and any other commands dont help) (can provide screen, as i dont have access to that save sadly)
