Hi,

2.1, nice!

PS: I increased the repeat count during testing since some times with low repeat count, no decals were destroyed even when throwing the grenade directly on it.
At one test it took 20+ grenade with repeat count = 1, area = 6.5 to destroy 4 decals on top of each other (4x sand-dune).

Context:
Made a Grenade with this effect:
{
type = "destroy-decoratives",
radius = 10,
from_render_layer = "decals",
to_render_layer = "decals",
include_soft_decoratives = false,
include_decals = true,
invoke_decorative_trigger = true,
decoratives_with_trigger_only = false,
repeat_count ...
