So, I'm flipping through some upgrade cards, and up pops one for a filter pack including Piggy, Firefly, and Beryl.
"That's weird," I thought. "I already have those."
So, just to make good and sure, I take a snap and check my filter options.
FUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUU-
After having bought every single filter pack long ago, I now have a total of five filters. Huh?
Is this a bug, or what?
