>>8794402Lego used to do this all the time. There's all kinds of one-off raised baseplates, some of them with weird and useless shapes stuck to them. The weirdest baseplate ever is this thing from 1728, and there was a fright knights set that had a "dragon cave" that really makes me wonder if lego acquired the stock of an unrelated toy company and slapped it onto one of their own sets.
