Where the heck did my XP Collider go?!?

I know the feeling, Lancemountain37! I recently nuked and had a bugger of a time finding the Krustyland gate. My XP Collider fortunately was charged before nuking so it stayed where it was originally - down in the bottom corner. Krustyland's gate was sort of middle-ish in Springfield so it was hard to find. The ones that weirdly stay out are the Springfield Heights currency earning buildings and another building I have no idea what it does. It's purple-y, gold and shiny and looks like it's stuffed with oversized donuts, but I don't recall its purpose.

Aside from the painfulness of the inventory system, I'm rather enjoying rebuilding Springfield. Hope you're able to enjoy your journey, Lancemountain37.
