Not sure if it's really a bug, but in the Chrysolia Hotel casino, the game will let you waste coins by buying TMs you already have (eg. if I have the Flash TM and try to buy another, the TM lady will take my 1000 coins and it says I obtained the TM, but when I go to my inventory it doesn't say I have two Flash TMs, and even if I did say that TMs are infinite use so it'd still be wasting coins).

I'm at the point right after fighting Aetila in Talis Resort (after 7 badges), where she asks you to meet her in Sheridan Village so you can explore Carotos Mountain together to find the Magma Stone. I've looked around Sheridan Village and Carotos Mountain, and I haven't been able to find her. Where is Aetila located?
