[Fixed - persists in 3.61] Disappearing treasure

[Míriel]

  Hi everyone, I think this bug hasn't been reported officially in the bug reports section (did a quick search for "treasure") but if it has I can remove or merge it with the original.
  I did a escort quest and received as reward a treasure location but there was none to be found in the two caves inside the region, only a random leather cuirass and a mother bear and her cub.
  I saw in some posts mentions of treasure disappearing after map maintenance and indeed it happened between the quest completion and me checking the caves so it may be the cause. I'll e-mail Sami the file after posting this.

Yes, please e-mail the save, I'll report back when I've investigated it.

There once was a bug that might lose treasures upon map maintenance, but it was fixed in 3.50 back in 2017.

Been checking things out here, and now it just might be that map maintenance can still clean out cave treasures. Bummer. Back to work then.

But you can rest assured that other type of treasures are safe from any data organizing harm and to be found no matter what.

Yes, it's confirmed, map maintenance can remove cave treasures.
It's also fixed now.

Fixed - persists in 3.61.
