I assume the room wasn't flag as indoors or am i wrong?

Guest Room of the Church of Enoch

This is a small room for guests to rest in. Many popular
Enoch priests and priestesses come and visit here. Reverend
Thatcher invested a small portion of the funds to have this
guest room constructed. It's not very large, but enough for
a couple guests to stay in comfortably.

You're right, it wasn't - I've readded the blade to your inventory.

Also, this points out a bug in darkmetal; your object should have been destroyed the moment you entered the room, not when you removed it. This has been fixed, so if you relied on this bug, be careful.

Stockade Main Building

The entire administration of the stockade is run from this
building. The commandant's office is always busy handling
one thing or another. A stone door marked 'armory' is to
the east. To the north, the corridor turns to the east
around a corner. To the south the corridor ends in a large
black oak door, presumably the commandant's office.
Obvious exits: north, south, door[c], out.

Stone giants caves in Firedrakes also seems unflagged.

Looks like for most of the older rooms, builders didn't flag them as indoors. I guess they didn't predict the coming of darkmetal =P

All fixed.
