MC-194769Nether Fortresses can generate without a lava room and corridor section.
The Bug
Nether Fortresses generate with exactly one 'lava room' (a room with a single source of lava in the middle), and then branch off into two sections, an unroofed bridge section with blaze spawners, and a roofed corridor section with chests and sometimes nether wart.
I found this nether fortress that is only the bridge section.

/execute in the_nether run tp @s 300 60 130
Sometimes fortresses generate without any corridor section because the bridge section cut off where it would go and that takes priority, but fortresses never generate without a lava room.

There is only a lava room without any chest and nether wart.
civiltensai Please see if this is still an issue in 1.21. We don't add affected versions that aren't the latest, unless it is the one where the bug appeared.
Still an issue in 1.21.1

Fortress has no interior section. Corridor next to lava pool is cut off by exterior generation so the fortress only has bridges and Blaze spawners.
