When spider queen is killed and the nest is dropped, picking it up shows as a tier 1 decorated nest. It was never decorated to begin with. A Webber has never been in this world or made any changes to the spider nests.
This clip shows the nest of the Queen being dropped, and it showing as a decorated nest before planting. Note: it's a normal nest when it is actually planted
(Nest the Queen came from was not decorated, no Webber has been around these nests)
1. Kill spider queen
2. Pick up dropped nest
3. Attempt to place. Den appears decorated
