Bugs in Hadean Lands?

I ran into some confusing moments, not sure if these are bugs or not. (After doing the first Big Important Thing.)

When making the dragon fulcrum for the first time, I put mercury on the lead rod to make an amalgam. Everything seemed to work properly. But when I tried to PERFORM DRAGON FULCRUM again, I would get stuck after picking up the mercury, with the game saying I didn’t know what to do next. If I walked back to Pyrics and made the amalgam rod by hand, then tried to PERFORM FULCRUM again, it would complete with no problems (and even switch to a different alien glyph for me).

(You are now in the Hadean Land, at Wreck.)

i
You are carrying:
a droplet of mercury
a thick key
a steel bolt

go to lead rod
The lead rod is in the Pyrics Store, as you recall. You head that way.
You push through the glass.
You make your way to the Pyrics Store.

Pyrics Store
This is a tangle of storage racks, mostly empty. The Pyrics Lab is to the west.

On one rack you notice a jar of camphrost lumps.

A silver coin and a lead rod lie on another rack.

A stack of firebrick in back serves as a crude ritual bound, complete with gestalt shelf.

take it
Taken.

go to drawer
The wire-drawer is in the Mechanica Lab, as you recall. You head that way.
You make your way to the Mechanica Lab.

[long room description]

put mercury on lead
Tilting the saucer, you dip the lead rod into the mercury. The mercury coats the metal, forming a white amalgam. You twirl the lead through the droplet until all the mercury is absorbed, and the rod is entirely white.

put lead in drawer
You slide the white amalgam rod into the groove, ready to be drawn into the device.

turn crank
You begin hauling on the crank, and the white amalgam rod is slowly drawn into the device. Soon wire begins spooling out onto the counter.

After several minutes of sweat, sore hands, and metallic creaking noises, the rod is entirely consumed. The white amalgam wire falls free, into a loose coil.

get amalgam
Taken.

perform fulcrum
You lay the length of white amalgam wire in the bound groove.
You take the chip of granite from the storage bin.
You make your way to the Under Ward.
You take the flask of vitriolic acid.
You make your way to the Materials Store.
The length of white amalgam wire is already in the bound groove.
You conjure a leverage symbol onto the chip of granite, using the first alien glyph.

(You are now in the Materials Store.)[/rant]

There are also various rooms listed in PLACES that cannot be gone to directly (“you don’t know of any such place”), which could be either privately-named or intentionally omitted. Most of the hallways are in this category, as are several of the rooms not on the map.

Finally, the disambiguation on GO TO AITHERY doesn’t give me any way to select the room itself:

[spoiler]>go to aithery
Which do you mean, the Aithery File clay mold, the lead Aithery File seal, or the Aithery?

aithery
Which do you mean, the Aithery File clay mold, the lead Aithery File seal, or the Aithery?

third
You don’t know any such location.

go to aistheta
Aistheta is in the Aithery, as you recall. You head that way.[/spoiler]
I was eventually informed that I could GO TO THE AITHERY ROOM, but this isn’t mentioned in the disambiguation.

The business about fetching mercury and the disambiguation of the Aithery should be fixed in the latest release. (The one currently on Humble/Itch, with serial 160522.)

The rooms omitted from PLACES are deliberate. The disambiguation would have been a nightmare if I’d tried to include every hallway.

Ah, should have checked for a newer version before posting. Thanks!
