[Embers 1.0.0] ton of 2x2 squares vault half-accessible

[Zeyphor]

the vault where you get a ton of 2x2 squares where you go from one to the next by digging is bugged in embers in such a way that you can only do one half of the vault which like the other has 2 multihued wyrms in the last square, and the other half is blocked off forever barring teleports, which according to the floor tiles(but not some patch notes) aren't supposed to be able to be done by the player anyway
