Дык вот.
The history:
Year 20. The fortress started.
Year 21. There has been made some adamantine weapons and armor.
All that were stacked in a handmade cave, behind the locked doors (1) and the bridge (2) that operated by the lever situated near it and covering the specially carefully channelled moat.
There were many other things created during everyday fortress life like food/drink/clothing/weapons/bags/bars/stones/bones and other trash.
Year 22. Orxz invasion repelled. Some preparations for adventure mode. And then i abandon the fortress.
Year 23. Started playing in adventure mode hoping to find adamantine stuff. Fool.
When i arrived to the fortress (maybe some days travelling from the start date) there were many friendly Orxz many stuff dispersed all around.
The bridge (2) was on his place, rised making impassable wall. Level made it passable ;-)
The second stop were at the doors (1), all of them were locked too, so i bashed them out before i saw that... NO stuff behind. WTF??!
Strangely the iron/copper/slag stuff i've made to train smiths were all on their places, nobody interested in it - and all that were lying openly in underground stockpiles connected with tens of stairs here and there.
I was deeply grieved seeing all my fruitless efforts during fortress mode.
But then i decided to search all orxz bodies (they were alive till then) - but they were carrying no adamantine weapons, nor armors, not a single one piece of my dwarves works (BUT those masterful works WERE in legends!, i've checked).
Some stuff i've found lying +-2 squares (map squares that are of 48 step) around the fortress and that were just some gauntlets, arrows and adamantine bars, but no armor, no weapons.
So... WTF?
My precious masterwork adamantine stuff dissipated from behind the bridge and doors. HOW?
Maybe it have to be stored in a pit without a stair/ramp?
But how then i take it out of there? Maybe adventurer can jump down a level and up and i don't know about it? ;-)
*Also i'm complaining about hemorroidal inventory shuffling system to wield a weapon in the right hand and put a bar in THAT ONE leather bag!*
