In SI, when you reach the part when you must talk to Mosh for the harp that will put the Rat Men to sleep, for some reason she is sitting in the chair at Flindo's house. This is with the latest versions of Exult and SI Fixes.
Attached is the best savegame. Simply walk into Flindo's house - she's right there.
It looks like this was intentionally programmed in, since she sits almost exactly where her schedule lists. There's no plate there, so she just sits instead of eats.
This might be worth adding some interaction with Mosh and Flindo in a mod.
I agree with KnightCaptain. It's as intended, as weird as it may be.
