The ghost lady in the haunted town gives some useful tips, but few people went back to talk to her, so they missed the solution to a side quest.

So, I added a line of dialog. The ghost lady is now inviting you to come back to talk when you need advice. You don't absolutely have to talk to the lady ghost, but it's easier this way.

I also fixed a collision glitch with the shroomba, it should be ok by now.

Thanks
