Strange glyph swap bug in Sil 1.1.1?

[kryft]

Before I forget, my recent game exhibited a strange issue where the glyph for Gwathraukar suddenly changed into a 'v' at some point in the game, and stayed that way until the end. I'm quite sure when I first met a Gwathrauko in that game, it was 'R' as usual, and every other rauko was 'R' during the entire game. I think my character never hallucinated during the game if that matters. I don't remember ever seeing this phenomenon before.

Very odd. I don't know what could cause that, but if anyone else has experienced it, please let us know.
