[Map] Having issues with Pokered Map Connections.

[supershadow64ds]

If anyone can assist me, I'm trying to connect maps in Pokered and having trouble (in a surprise to absolutely no one).

The Left is the map edge taken from Pallet Town. The right is the exact same location, taken from Route 1.

For some reason, trees end up showing up and I've no clue why. It's only graphical as I can walk right over them, and refreshing the map by walking away and coming back shows the proper tiles. If it'll help, here's the header for each map:

Pallet Town:

Spoiler:

PalletTown_h:
db OVERWORLD ; tileset
db PALLET_TOWN_HEIGHT, PALLET_TOWN_WIDTH ; dimensions (y, x)
dw PalletTown_Blocks ; blocks
dw PalletTown_TextPointers ; texts
dw PalletTown_Script ; scripts
db NORTH | SOUTH ; connections
NORTH_MAP_CONNECTION PALLET_TOWN, ROUTE_1, -12, 0, Route1_Blocks
SOUTH_MAP_CONNECTION PALLET_TOWN, ROUTE_21, 0, 0, Route21_Blocks, 1
dw PalletTown_Object ; objects

Route 1:

Spoiler:

Route1_h:
db OVERWORLD ; tileset
db ROUTE_1_HEIGHT, ROUTE_1_WIDTH ; dimensions (y, x)
dw Route1_Blocks ; blocks
dw Route1_TextPointers ; texts
dw Route1_Script ; scripts
db NORTH | SOUTH ; connections
NORTH_MAP_CONNECTION ROUTE_1, VIRIDIAN_CITY, -3, 2, ViridianCity_Blocks
SOUTH_MAP_CONNECTION ROUTE_1, PALLET_TOWN, 12, 0, PalletTown_Blocks, 1
dw Route1_Object ; objects

I've changed the size of Route 1. Instead of it's normal dimensions it's X by Y is now 40 x 9.
If it helps, the block that's showing up isn't related to the Border Block of either maps. I checked by changing the border block of both maps to something other than the 4 trees and there was no change.
