Repro steps:

1. Load world with mekanism pipes covered by facades:
   
   
2. Save and quit to title
3. Load another world and go to same coordinates
4. Observe phantom facades:
   
   

Can you still interact with the pipe stuff?

i thought that wasn't a thing anymore in the mod

same is happening to me on 1.19.2 forge 😞 the pipes still work for me but you cant see the facade block, and when you try to step on it the player starts glitching up and down really quickly. it must still be there somewhere though bc if you go in survival and use a wrench it will give the facade back.
