[2.0.15] Landfill bug

[azalulu]

What did you do?
https://youtu.be/0I-pja9ZnBc
I placed some quality landfill
What happened?
It became normal when I mine it back
What did you expect to happen instead? It might be obvious to you, but do it anyway!
It would be mined as landfill of the same quality as when placed
Does it happen always, once, or sometimes?
always

It is minor but can hurt if accidentally placing some landfill I've been storing for for quality biochambers.
