https://prntscr.com/c2cdko Not sure if this goes here but you can talk with every trainer on the goldenrod gym even when you are on higher ground than them.

All those areas i mentioned are in the johto region.

Most of those are map related.

 

the glitter lighthouse is a genuine error, which i will fix when i get home later on.

 

The 'black ceiling' is infact the top part of the wall, which u are seeing from above, not an error.
