Something you did in the recent patches seemed to have broken the "reset party" ghost in HRCS, it doesn't properly clear the party. Your chosen party members stay in the party screen even after resetting, yet if you try to go outside it says I should pick atleast one party member. Now if I go and choose Sakuya to the party, my speed actually decreases since she can't actually get into the party...
EDIT: Is there a reason SDM remains closed after Patchouli & co. rejoin the party? The crafting ingredient shop is in there and it would be nice to have access to it now that some stuff could actually be crafted without extra grinding.
EDIT2: Quite a few of the pitfalls in the cave to Makai send you to a spot downstairs where you can't move, forcing a reset / Emergency Stairway. Also, the save circle thingie that disappears should apparently change something in the pitfall room, but nothing seems to happen (I looked at your LP on Youtube to confirm this, it worked that way in the video).
