I'm having the same problem. My roof is gone weather I'm in build mode or live mode. And weather I have my walls up or the walls up cut away.
@emofallenangel20 There is a bug report on missing ceilings here:
https://answers.ea.com/t5/Bug-Reports/OPEN-Disappearing-Ceiling-Glass-Roof/td-p/7182946
If it matches your issue, please click the button Me Too in the first post, and describe your issue in the thread. Screen shots are always welcome. The workaround posted in the thread is to delete any glass roofs placed on the same level as your disappearing roof.
If it doesn't match your issue, please describe more about it, and add screen shots. You can attach them to the post directly.
