disappearing metal floors

Hi mighty admins.
I built 3 metal floors on my humble base to start to get some height the other day (9 August), but today they have disappeared...any chance I could get them restored or replaced? Having just started such small building losses are hefty! Base is at 030063.
Thanks, mmb
PS...hilarious youtube vids from this server

Oh, those...That's because ramps into the sky are not permitted on this server without supports. That's why they were deleted.

Ah bugger...didn't see that guide soz...I guess the 8 I added last night will be wiped by the time I get back on too...ooops. Is there any way I can get those refunded as part of a rooking error!
Thanks for explaining Artemis!

I will refund them when I log back on tomorrow. It’s currently 0320 here.
