When i go to sleep on my world i can see the electrical connector's and steel wall's to disappear until i wake up, this might again be another optimization thing but i don't understand why it would be there so im treating this like a bug

using version X4562

I've seen it happen too. It's harmless, and it only seems to affect wires.

Sounds like an issue caused by the change in player perspective, although steel walls and wires use standard TESR rendering. Does it happen to larger modeled machines or vanilla tile entities like chests too?
