Some more criticism to consider : I'm finding that party members that disappear are really hard to find. I barely found a character that disappeared from turning into a tree, and I cannot find a character that disappeared due to the hieroglyph effect. It would help if there was an option to just tell you where they are, or have them show up on the party member page in their disappeared state, because I've looped the tomb like 10 times and can't find the missing party member.
EDIT: I think there's a bug with the hieroglyph. Sable was a zombie/skeleton, had their soul in a soulgem, and was turned into a hieroglyph. I assume you're supposed to use the pickaxe on the blue crystal wall to find the missing party member(I couldn't find them anywhere and the sign next to it seems to reference the status description in the journal with the mention about forgotten party members). I returned Sable to her original body via an altar and the soulgem and it returned her body. I'm afraid the save might be bugged now although I dunno.
