Unenterable transporter vault

[Monsterracer]

I've fully explored the level and found all 6 stairs. Is there a way into this vault?

The glass walls are indestructible.

The screenshot inline looks broken from here.

No chance of trapdoors down from another level, maybe a shaft? Dunno but might poke around and check.

I'm pretty sure that vault is nemelex_the_gamble. Only one of those two side vaults is accessible, chosen at random, and you don't find out which until you try it out. You got the bad result. If you do find a way into the one you aren't supposed to be in, it is a bug that you should report.
