Got some time!
The pillar is a minor tile error, and the bridge is a missing flag (I made the flags that affect the bridge passability before I made the scout and the Fairy Rings). Fixes work and should ship with the next patch.
I'm trying to reproduce the "Now Loading" issue and I still can't quite do it on my machine. Are you still copying the data files over? I added a new graphic to the Doodads folder in Images that loads in the Fairy Ring hub, so that might be the issue since that's not in the data files.
