I have given in and fixed many issues with the original quest. I did not make any scripting changes, so the pits will be just as buggy as they have always been. But you can use your existing save file, if you want.
Changes include fewer shutter rooms, the magic armor no longer uses magic, the lightning medallion gives straight-up infinite magic instead of just slowly restoring it, the cane has improved range, the secret tunnel boss is less stupid, and palette changes, among many other things.
Look for the update to be ready soon after this post appears. As of right now (3:33PM EST), it has not yet been processed.
