On the seed 5990050710196661415 at the coordinates -36 94 -3, there are 4 scarecrows in view. According to the mod's code, each scarecrow should generate 70 chunks apart.

This is replicable in many modpacks. The one I am testing in the screenshot is BMC2 Fabric. I have also seen reports of it happening on the Forge version of Additional Structures.

Latest Fabric Loader version, latest Additional Structures version

MC version? Mod version?

1.20.1 fabric
AdditionalStructures-1.20.x-(v.4.2.0)

Happens on 1.20.1 Forge as well, modpack is BMC4 Forge
Seed is -5360922093071205614

Many apologies - this is actually the Explorations mod doing this. It spawns identical scarecrows that are marked as features instead of structures.

Sorry for the bother!
