Headbutt tree Error

[futuresushi]

Hello!

I ripped my save from my VC Crystal out so I could play it faster in BGB. While playing I used this headbutt guide to find trees that would give me Aipom and Heracross. Both show up as illegal saying they can't find a tree that matches my save. Given I used only a guide to pick the tree, I'm not sure how that is so I'm clearly missing something.

Attached the whole save for reference. Aipom and Heracross are in BOX 1

Looks okay to me:

For Aipom,

Not that this check matters, since Aipom can be normal and rare tree spawn.

Next, for Heracross,

Referring to previous image above, rare tree is possible for that Route.

Hm any idea why the mons have illegal flags on em then? False positive?

Current tree list: trees.txt

I don't see route 42; odd.

[futuresushi]

Oh if Route 42 is fully missing from the reference files that would explain it!

My suspicion is that the "Whirl Islands" entry was mislabeled (location ID), and should be for Route 42:

The count of trees lines up with what's in the image (40 total), with 10 (correct) inaccessible trees).

For those wanting to manually interpret the coordinates, step X tiles to the right and Y tiles down, with (0,0) being the corner tile.
