Describe the bug
The construction recipe for "Mine Downstairs" doesn't seem to recognize the rock floor.
Attach save file
Phobos-trimmed.tar.gz
debug.log
Steps to reproduce
- Level Fabrication to 6 and Survival to 4 (mine shows up as red on the recipe for some reason, but the other screenshot shows I have it at 4)
- Gather all materials required for Mine Downstairs recipe
- Attempt to use the recipe on rock floor (in my case beneath a burnt-down house)
Expected behavior
Recipe succeeds and a downwards shaft is made
Screenshots
"rock wall" floor listed on the sidebar

Recipe does not recognize it

Skills are high enough, despite Survival showing as red

Debug menu info. I attempted without the debug menu first then tried to force the terrain with it, to no avail
