Title: -Fix (032da23c894468921203ce8557cf4dfcf6f9c728): translation errors in Tile_GetTileInDirectionOf

Looking for some independent verification. Not sure what the overlays are all about.

1. dir should be incremented by 31 (0x1F) instead of 29.
2. i should not incremented, making it loop until a valid tile is found.
