Well, I found a few more, very minor ones:
Walking on the water! lol, I You can walk there to the left 5 or 6 more steps, and then things become normal.
Tile error.
You cannot Surf talking to the water there, it sounds click and nothing else.
This one is odd, Normal-type moves are neutral to Rock-types, at least Pound was not not very effective against a Nosepass.
And items respawn also in the cave.
Also, a little question, in the document it says Aron appears in the Masked Man Cave, but I've been there for a while and haven't found it. Is it very rare?
This game is so good, the quality of your hacks is amazing, and the best is the more games you make, the better they'll be as you are getting a lot of experience hacking!
EDIT: lol, found the Aron just after asking you! Also, Pound was again neutral to it, so Normal-type moves are neutral against Steel and Rock Pokémon.
