Hello. I am currently in the Butwal Island part and I encountered some kind of a bug (I don't know if it's really a bug, or a glitch, I don't know the difference between those two) as soon as I enter the Butwal Island Map. Every time I walk one step, I always encounter Sunflora. Literally every time, every step. I also encountered this problem in Pokemon Light Platinum, too.
Even if you use Repels, they still won't leave. I tried checking with the Advance Map Editor and it shows the the Map has some kind of error.
