unfortunate bug, nothing that can be done about it
Please don't rush a master, when you do you will get a lot of bugs
revert to an earlier version of the game to fix this issue
you'll need to go to Beta 4.0 o be able to get through the house
If they have fly in this game don't show how to get it assume they are using a fire red gameshark code
its the end of the beta, you could use Fire red walkthrough walls to go through, and see some of the next event or two of the game, but extremely buggy, most houses will take you back to Pallet Town, some characters are not intractable, and noting is solid.
