Multisphere trace ignoring the same instances every time

Hey all I have a simple world generator made up of tiles, attempting to remove some with sphere traces works pretty well except for some reason in certain map locations it will ignore the same instances of the land tiles every time.

Everything is generated on begin play and its the exact same spot every time. I’m not really sure whats going on since its random gen, but it’s the exact same locations every time it’s almost like the sphere trace just decides to do half and says ehh ■■■■ it.
