The same thing happens with me while using Following Pokemon script, so I ensure that I disable following Pokemon as soon as the player enters this map.
Hi! I'm compiling tilesets from HGSS for my own game. If you'd like, I can share them. I have compiled them from the ones ripped by Sir Malo.
However, I shall warn that they have some parts missing (originally from Sir Malo's rips) and you may get struck in the between while making maps.
Also it...
