Spyro 3 Year of the Dragon Sheila's Alp Glitch

I'm wondering if anyone else has this problem: I pay Moneybags to free Sheilaa complete her level, than while in Seashell Shores, I go into Sheila's area, come back out, and my atlas says I havent freed Sheila! What's more, Moneybags is back outside Sheila's Alp portal, as if I never freed Sheila. I have to go back to her level and complete it again (as in getting the egg that opens the portal). Is there a way to fix this?

Problem Solved. I switched from PCSX to ePSXe. I'm curious why that happened, though.
