Yes, we know, Hakusan Heaps was never meant to have a 20th floor. Yes, I suppose that made it a "bug". But, dear developers, please consider unsquishing it. The Sandbox group (1332 members as of this post) had adopted that hidden space as our Secret Lair. Accessible only by teleportation, it was a place where player-written missions and quests could easily be distributed, where resources could be shared, and where people could meet up prior to embarking on fun flash mobs. Maintained entirely by volunteers from the Sandbox group, tp scripts to the lair were available to anyone who asked for them. In "fixing" this so-called "bug" you have destroyed one of the very things that makes Glitch great for so many players.
Please, please, please give us back our Secret Lair!
