[Question] why new terrain tags cannot be useful in Map "Route 8"

[Aceamuro]

#Please forgive my poor English, this is not my mother tongue 0w0
i developed the Reflection script for making it possible to show Reflection in the mirror tile.
i made a new terrain tag whose ID is 17 and new property "" is True.
it works in everywhere EXCEPT map "Route 8"——it alse works in new map.
so,why it happened?
Is there anything special about the map "Route 8"?
Although this does not affect my later work, I still hope to understand the reason for this problem out of curiosity. =w=
