Short description of error
when I delete animation of one environment it also deletes animation of 2nd environment

Exact steps for others to reproduce the error
step 1: animate any property of any node in the world tap
step 2: duplicate the world
step 3: try to delete the animation of any one of the world without deleting other

note* I am not sure if I explain it well because of my poor English
so I have attached videos.
which will make more sense.

Can confirm, will check.

Technically not a bug, just that Action data-block remains shared between both materials… But agree it should probably be duplicated as well by default (until we take userpref settings into account).

yes this doesn't happen if we duplicate object materials
this problem is only in the world (environment)

@Philipp Oeser (lichtwerk) T81267 is now fixed (was unrelated lower-level issue), so think you can now commit the fix for this issue. ;)
