Something, or more likely someone, who is currently completely undetectable, has now taken said crystal.

Spoiler alert: It's just Gaster and now said crystal is in his inventory. In fact, if you didn't blink, you might have even seem him temporarily exist right next to the crystal before he disappeared again with it.

I mean, hell knows what he's planning to do with it, but it's probably something important. Maybe.
