Crash when copying walls after using Fidwell's Shift Map plugin

[astraylife1]

I used Tidwell's shift map plugin to shrink a large map and shift it over quite a bit. Now when I use scenery manager for this particular park, the game will crash any time I copy a wall and move the cursor outside of the scenery manager window. I am having trouble replicating this particular issue on other parks after shifting the map so I'm not sure exactly what is happening. Github won't let me attach the park file so here is a link to the affected park file: https://drive.google.com/drive/folders/1lQlMtktZawD5G4N2LiRPh0m1vKuhuDSD?usp=share_link
