Let me know if you're able to zero in on it. I did a basic sanity test, ran through the scenario a few times on a fresh save, but no luck. Unfortunately if it's not something that's happening frequently, or easy to reproduce, I'll probably have to leave it for now. RPGMaker's scripting and interface is kind of all over the place, so at a certain point I have to settle for "good enough." But let me know if you're able to get a closer lock on it.
