Sold a Ring of Hindrance (unIDed) to a number "9" shop in a small town (Eriador Town) and it did not ID the rune. Furthermore, the Ring disappeared and did not show in the shop's inventory (it didn't sell rings to begin with).

More Price Stuff
 

Prices: Enchanted ammo is still far more valuable than anything else; a stack easily goes for 6-10k, while most armor egos are a few thousand and the weapons generally aren't much better.

Repeatable Crash
 

Just tried to recall back into Amon Rude DL30 after leaving it after killing Mim; the game freezes when the recall actually triggers.

Maim Foe on Blackguards sometimes gives no attacks, only the stunning; and if that happens against a sleeping monster, you can stun them without waking them up. Not sure if the first part's intended (the spell description is ambiguously worded), but the second part definitely seems weird.

Tested it in the dungeon, it didn't crash the game but there was a mysterious "you are thrown back in an explosion" which I presume was caused by the DD since it had no other visible effect.

Dungeon Entrances
 

At least the dungeon entrance at Talath Dirnen DL29 doesn't generate; I thought I saw complaints about other entrances to dungeons that aren't Amon Rudh, but I'm not sure.

Dungeon entrances to Nargothrond (in Talath Dirnen) and Tol-In-Gaurhoth (in Sirion Vale) should actually work now.

Ego Knowledge Menu
 

The ego knowledge menu lists pretty much every ego as having most resists, nearly all of them at 80%.

wobbly and I were looking at the code here for "reversing" a resistance. The actual intended purpose of the code was not immediately clear to either of us, but I'm pretty sure it's not achieving it; it's deducting a (presumably positive) resistance level from RES_LEVEL_MAX (which is 0), making the res_level go negative (meaning negative damage taken), but there's code later to tone it down to 80% resistance. wobbly's look at older FA seems to indicate this code originally turned resistances into vulnerabilities, and got broken when RES_LEVEL_MAX (formerly 200, now 0) and RES_LEVEL_MIN (formerly 0, now 200) were flipped around.

Yes, you're right.
