ToME: the Tales of Maj'Eyal

I bring this up, even though I reported the bug in-game, because it looks like the sort of bug I might be able to fix myself. Looks like.

Lua Error: /engine/Birther.lua:57: /data-ashes-urhrok/birth/race_cosmetic.lua:33: attempt to index field 'cosmetic_unlock' (a nil value)

The reason I think I might be able to somehow fix it on my end is that some time ago, I modified the allow_build file to have demonologist set to "true" before I did the actual unlock work. (This was before ToME Tips came into existence; I wanted to get a look at what the class actually did and its implicit flavor.) When I tried to set it back to "false", though, the game kept setting it back to "true". The Demonologists and ok=false lines make me wonder if something got stuck in my attempts to revert the class, and only just now began interfering. I will admit that I'd been away from the game for quite some time, so I ended up patching straight from 1.5.0 to 1.5.5.

Are you on Steam? If so, it's almost certainly a file being aggressively restored from the cloud.

No, not on Steam. I downloaded the game through the launcher.

I've encountered the same issue (non-Steam install). I can create a new game in t-engine v1.5.3 but not v1.5.4 or v1.5.5 due to this bug.

Please make sure you have both the latest version of ToME *AND* Ashes, this sounds like the culprit

Sure enough, I had to re-download (or thereabouts...) Ashes of Urh'Rok. (So much for auto-updating on start.) It had been reading version 1.4.0. Now it's 1.5.0.

All hail DarkGod!
