Now that my problem is solved and since I discovered another one I hope it's ok if I "reuse" this thread for another problem
If you use the terraformer on the moon it doesn't terraform blocks with footprints on them, it says there no valid blocks in bubble, so it probably doesn't recognize them as regular blocks for some reason, if you break and place the blocks again it terraforms them.
I don't know if this is a bug or glitch or it's just my old computer but I thought its worth mentioning
Steps to reproduce:
1: start terraformer on the moon
2. Walk around on some moon turf blocks inside the bubble
3. Watch as the blocks around them are terraformed while they remain
