Haven’t tried, but it’s nowhere near where I wanna be.
On a side note, I brought it almost to my new base… but I have an outpost nearby and lots of water between. I could build some more bridges, but geez, I’ve done that already quite a bit.
I also have another turtle that’s NOT 20. I have a few on ice, so I may break bonds with that one and replace it. This level 20 was hard enough as it was, especially maneuvering other bases where I couldn’t place it down.
EDIT: just checked and no. Map room doesn’t work either.
