What the hell, it won't save!

So I spent like two hours making this sick ass contaption but when I go to save it It seems to wrk fine, like the button is clicked, no lag no crash but it doesn’t actually save, at least it doesn’t add it to the load games list. What the hell, that’s really annoying, especially cause when I restart it, there’s just no trace of me ever building it, can someone please help?

Don’t use saves. Use the Adv Duplicator.

Can upload to Most Servers
Will save to text file for upload
Won’t break too much

Sometimes welds and wheels are a bit weird.

Note saves don’t even work now.
