Awesome-yet buggy-ice sheets!

I was messing around in Winter when some pengulls jumped onto my giant dock set.
They made a nest, and as a good neighbor I promptly murdered them all and broke the dock under it for fun.

It left this really cool ice sheet that resembles a frozen over lake.
Sadly I can't walk over this and items fall right through it like it doesn't exist so it looks really weird but it is pretty cool to see fish swim under it.

I'd love if this could be made into an actual feature but if not, maybe have them vanish when docks break?
