I downloaded a bunch of the nightlies and managed to isolate the specific update that introduced the problem. It was working in this one:

24 Oct 2011 at 19:39 UTC, revision 883bab2

And then broken in this one:

24 Oct 2011 at 20:51 UTC, revision de47bfb

Nicely done - that narrows it down exactly. My apologies to the UTF-8 folks, because it's not that at all. This was a change to how V does capitalisation. I've no idea why it should glitch on Windows, but
I've opened it as #1572.

EDIT: this doesn't make sense. de47bfb is a one-line change - the main capitalisation work was earlier, before 883bab2. That one line is related to prompts in the game, so I don't understand how it can affect dumps or spoilers.

That's very weird, because chardumps definitely work for me in 883bab2. However, I have also noticed something else wonky with the caps that apparently pre-dates that change: monsters referred to as 'it' or 'the' are not capitalised at the start of sentences, i.e. you get "the Village idiot wakes up." instead of "The Village idiot". So maybe something's buggy with the original capitalisation change and for some reason that one line of cleanup caused the prexisting bug to break the dumps? :confused:

Just found an awsome randart in 3.3.2

The guantlets of Randen [3+46] provides resistants to fire, prevents paralyzes, activates for restore life levels, found on level 20

What artifact is this based on? It's extreemly powerful

Ehh, besides the AC it's nothing much; it just happened to be useful when you found it.

I don't think there's any way of knowing what it was based on.

I just noticed a an extra benefit not listed, it also restores your stats when reduced, that isn't listed on the item properties, by the way I find it very useful as im playing a half-troll warrior.

Wasn't that a side effect of restoring a level with Restore Life Levels?

Yes if you lose entire level, and not just XP. Kind of loophole to fix time-ruined stats, but can take a while if you are at clvl 50 with huge XP buffer. I don't know if that is worth "fixing", it just creates one more strategy to fix stats.

It should now say "Based on Something" in the dump text. Not sure if that only shows up in the spoiler, but it should definitely be there somewhere.

Once game is over create a spoiler for artifacts. In the spo file you will see which artifact it was based on . At least it worked in 3.2
