Hi all,
I was following the tutorial on the wiki: "Bethesda_Tutorial_Layout_Part_1". Creating a basic interior space. Following the steps, I placed four sides of the room and then placed the floor/ceiling saving every minute or so because the Creation Kit is rather unstable on my PC. Then the CK crashed. When I opened up my plugin again, the floor was there, but some of the walls were missing. The strange thing is, placing the floor was the last thing I did. The missing walls were placed in an intermediate step! What could I have done wrong that caused not all parts of my plugin to be saved? I'm pretty sure I followed all the steps in the tutorial correctly.

I'm hesitant to continue because losing work on the tail end of my progress is one thing - I can pick up where I left off. But arbitrarily losing work somewhere in the middle of the design seems more serious to me and I'd like to understand what I did wrong. Please let me know if I can provide more details.

Thanks.
