buildings and blocks placed by spatial storage are seemingly ignored by weath with Rain etc going right through them as if they're not there.

Ripped a building from the world using spatial pylons and a correct Spatial IO Setup and placed it down in a new location whereupon I noticed weather effects etc seeming are ignoring the blocks, breaking a block and replacing it caused that specific block to begin being registered by the weather however.

I did de-load the chunk then re-load it but unfortunately it didn't seem to fix the issue.
