Fix: Doors from cathedral to cathedral save access not being marked as open

[Miepee]

I forgot that it's the amount of "lockable hatches" present in the room that determines whether the clipdata will work correctly.

Also not sure why in the past door 0x6E was tried to change to begin with? It's really strange because:

1. that's the door in puyo palace that goes to cathedral
2. in vanilla that is already an open hatch. so the lines actually did nothing...
