I already have 128k Flash .__. ...
Also, the screenshot it's from the Beta 5.6 ._. ...
EDIT:
And it still happens in 5.65 ._. ...
Yet, in some other grass at the same Route, it doesn't.
It isn't a Random Freeze at all.
EDIT2:
Now i just found a tile error, in the Route 118, at the East of Mauville
EDIT3:
I found a cave in the desert of Route 111, but it doesn't have a warp so i can't go in..
And it seems to be Regirock's cave......... so i will probably not be able to do the method and catch the Regi Trio... thanks..
EDIT4:
Another tile error in Mossdeep Pokémon Trainer Fan Club's House
