Budget cuts and shifts/restructuring of Deep Blue Creative (probably for the better) I would guess as continued reasons. At this point a gist of a story would be better than the nothing within those walls with potential now.
I was on it 2 weeks ago and was shocked they got rid of the storyline. The last time I was on it was 19 years ago. But they still have the giant Medusa head. It doesn't make sense to keep it if there's no more story
