Those Who Lurk in Shadows (II) Broken?

Or perhaps better known as the 'collect the lights' mission in Fei'Yin, from ACP, which rewards either an Azure Key or Mark of Seed. I was checking out the new mobs in Fei'Yin, and figured I'd get an Azure Key while I was there. I've collected tons of these (used to get them daily for a good while), but today one of the Seed Afterglows seemed to be missing. Specifically, the yellow one. In its room now are Sentient Carafes, which are magic pots that check IT at 90. I have no problem with that, since pots only aggro magic, but I don't know how putting different mobs in the room suddenly made the Seed Afterglow disappear... a glitch or simple accident, perhaps? Has anyone else noticed this, or was it just not loading for me for some reason?

This happened to me today. Was wondering WTF and was looking around since i only had 3 left and then the IT ghosts decided to aggro (lvl90) was /BLM for warp and was pissed that i couldnt find the yellow. If anyone knows where to find it now would be nice >_<
