Well, I was able to finish gluing the remainder of the 6" tiles, and I got the office space a little more organized. Sadly, I went to take a look at the Harbormaster walls I was working on the other night, and apparently the file got corrupted. It only opens the first six layers, which means I've lost most of the work I've done. Gah.
I might have a backup recent enough to make me feel a little better, but as it stands, it feels like a big setback.
