I have more to say about all of this, but firstly I think I fixed the subarea corruption issue - can you retest on the same seed and confirm? If not, please provide the seed and options you chose so I can keep working on it.

I'll work on that too.
Anyway, longer answers:
- World mixing is hard because SMB3 worlds are unidirectional and SMW worlds are omnidirectional and frequently have multiple ways in or out, so there's not really a clean way to make it feel like both progression and mixing. One idea I had was mixing Star Road and Warp Zone but I haven't put a ton of thought into making that work. I do want to shuffle SMB3 world order at some point at least.
- I don't want Switch Palaces to be vanilla forever. I think I want them to be possible rolls for Toad Houses eventually.
- Stay tuned on SMB3 inventory.
- I absolutely could implement progress saving, and in fact I think SMW's works by complete accident, but I've poisoned SRAM so bad by stuffing it full of important cross-game memory that I fear trying to actually keep it sane over power cycles. God knows what state information would leak strangely or stop working after a power cycle.
