I just landed on a modded planet called Moshine, and this doesn't seem to work on "Moshine dry swamp" tiles. You can seemingly build on them normally, however, this mod's functionality doesn't work on the tiles at all
Thanks for the report. Space Age made building on tiles weird in a lot of ways, and it's gotten a little easier to make it work in weirder situations as the later patches have come out. I'll revisit it eventually to try to improve the mod compatibility again.
Sounds good! It's no rush - honestly at some point I'm going to just concrete pretty much everything so this problem won't matter anymore, but it did throw me for a loop when I was getting setup for the first time on this planet
